Jackson, a 2008 second-round pick out of Cal, who led Philadelphia with 961 yards receiving last season, was scheduled to become a free agent on March 13.

"We want DeSean to be an Eagle for the long haul and this is a step in the right direction to accomplish that," general manager Howie Roseman said. "DeSean is a talented player and a proven playmaker in this league and we look forward to him continuing his career in Philadelphia.

"It's our understanding that he has the same desire. We will continue our efforts on getting a long-term deal done with him."

Jackson made the Pro Bowl in 2009 and 2010, posting totals of 229 catches, 4,085 yards and 21 touchdowns along the way. Last year, like a lot of Eagles, was a disappointment for Jackson, who caught just four touchdowns as Philadelphia finished 8-8 and out of the NFC playoffs. -- (AP)

Welcome to a new low in Philadelphia's miserable season.

"It's ridiculous to have this much talent and be where we are," Philadelphia offensive lineman Evan Mathis said.

Marshawn Lynch bulled through the Eagles for 148 yards and a pair of first-half touchdowns and the Seattle Seahawks rolled past the Eagles 31-14 on Thursday night, Philadelphia's fourth loss in five games.

Making a quick trip to the West Coast after losing at home to New England, the Eagles (4-8) just about waved goodbye to the postseason trip that everyone assumed was a foregone conclusion before the season began.

They might as well have stayed back in Philadelphia.

"We've got a lot of good guys. I can't complain a bit about the effort or the work ethic that they put forth," Reid said. "I've got to make sure that I get them in a better position to make plays."

Making his third straight start in place of Michael Vick and his two broken ribs, Vince Young couldn't find the same magic he did in the 2006 Rose Bowl when he led Texas to an upset of Pete Carroll and USC.

Young's first pass of the night was an awful interception thrown right to Seattle safety Kam Chancellor and nowhere near an Eagles receiver. That was just a precursor. Young threw a career-high four interceptions in all, including a swing pass intended for LeSean McCoy that David Hawthorne stepped in front of and returned 77 yards for a touchdown with 4:24 left to put a cap on Seattle's third win in its last four games.

Three of Young's four interceptions led to Seattle touchdowns and the fourth time, the Seahawks (5-7) took a knee at the Philadelphia 1 to end the game.

"I really felt like the effort was definitely there. I can speak from the offensive standpoint, overall we were driving the ball pretty well," Young said. "Seattle did a pretty good job of coming out and playing good."

Young finished 17 of 29 for 208 yards. McCoy got more chances than he did last Sunday against New England when he touched the ball just 14 times, a number that drew criticism from Eagles fans believing the leading rusher in the NFL deserved more opportunities.

McCoy finished with 84 yards on 17 carries and added another four catches for 49 yards. But he was upstaged by Lynch.

"This is really tough. Knowing that this is a good team, but I feel like we are a better team," McCoy said. "No disrespect to them, they played hard, but knowing that they are a good team, but we are far, far better. Way more talented. We didn't get it done. We played poorly today."

The Eagles played without Vick, CB Dominique Rodgers-Cromartie and WR Jeremy Maclin, then lost CB Nnamdi Asomugha to a neck/head injury late in the first half.

Still, Philadelphia pulled within 24-14 early in the fourth quarter when Young led a 17-play, 80-yard drive that ate up more than 10 minutes of the clock. The drive included a fourth-down conversion inside the Seahawks 10 and was capped on a 2-yard shovel pass from Young to McCoy.

Young then drove the Eagles inside the Seattle 35 on their next possession with a chance to make it a one-score game, but failed to see Hawthorne lurking in the flat. Seattle safety Earl Thomas jumped Young's primary target and by the time he came back to McCoy, Hawthorne was ready for the pass.

"He was expecting him to be open and he wasn't," Hawthorne said.

Philadelphia's bigger issue was its inability to slow down Lynch, who had touchdown runs of 15 and 40 yards in the first half, each another showcase of his hard-charging style. His 15-yard run in the first quarter saw Lynch bull into a pile, slip through the arms of linebacker Jamar Chaney and escape into the clear for the score, his eighth straight game with at least one touchdown.

"I couldn't figure it out myself," defensive end Trent Cole said. "I thought he was caught up in there and all of a sudden he popped out. When he popped out I didn't know who had the ball."

Lynch's next score came on the first play of the second quarter and gave Seattle a 14-0 lead. The flow of the play went to Lynch's left, but he immediately cut back right and found open field, beating the Eagles defense to the corner and going 40 yards untouched.

It was the second-most yards rushing in Lynch's career, behind the 153 he had in his rookie season with Buffalo against Cincinnati, and the most for any Seattle running back in more than five years.

Golden Tate added a toe-tapping 11-yard TD catch from Tarvaris Jackson at the back of the end zone in the third quarter to give the Seahawks a 24-7 lead.

Jackson was 13 of 16 for 190 yards and the touchdown, finishing with a career-high QB rating of 137.0. It was a strong rebound for Seattle after blowing a 10-point lead last Sunday in a loss to Washington.

"The whole thing was about finishing," Seattle coach Pete Carroll said. "That was the focal point and we wanted to execute really well. We did a lot of good stuff."

Asomugha did not return after hitting his head on the knee of Seattle WR Mike Williams. ... Backup safety Colt Anderson sustained a torn ACL in his left knee. ...

Vick had one of the best days of his career with a personal high of 416 yards passing and 30 completions, added 75 yards rushing and two touchdown passes. It was all for naught as the Eagles lost their third straight, blowing a 20-point lead and falling to San Francisco 24-23 on Sunday.

"We've got to dig deep," Vick said. "It's right there for everybody to see what is taking place, how it's been done, what hasn't been done and what needs to be done."

Vick did about all he could, only to see the Eagles fall apart on defense in the second half. He was at his scrambling best and his one interception was tipped by DeSean Jackson directly to cornerback Carlos Rogers. His bruised right hand, protected by a padded pink glove, didn't slow him a bit.

Asked if some restrained playcalling by coach Andy Reid slowed his team and allowed the 49ers to rally, Vick shook his head.

"No, it's not the coaches being conservative," he said. "I think it's us as players having to figure out what needs be done in the moment. And everything has to be right, everybody has to be in the right place. Certain times in the game, you have to gut check.

"Some people have it and some people don't, but we're going to find out who's got it."

Instead, it was the 49ers who produced the gut check. Philly's defense fell apart in the final 30 minutes, and Frank Gore capped a 77-yard drive with a 12-yard TD run with 3 minutes remaining.

Then David Akers, the career scoring leader for the Eagles who joined the 49ers as a free agent in the offseason, kicked the decisive extra point.

"It's unacceptable to give up a lead that size in the second half," defensive tackle Cullen Jenkins said. "If we don't win, we're just a bunch of talented people who haven't done anything, and there's a lot of teams like that."

The 49ers (3-1) are talented enough to lead the NFC West after breaking a five-game losing streak against Philadelphia (1-3). The much-maligned Alex Smith went 13 for 17 for 201 yards in the second half, with TD passes of 30 yards to Joshua Morgan and 9 to Vernon Davis. Then Gore, who didn't start because of a sprained right ankle, powered into the end zone, and Akers finished it off.

The victory meant plenty to Akers, who made a 37-yard field goal, missed from 44 and had one blocked from 45. He left the Linc with a huge smile on his face.

"To hit the last extra point, it's like hitting a 50-yard field goal," Akers said. "It still counts as one, but it puts you up."

Akers' replacement, rookie Alex Henery, missed from 39 and 33 yards in the final period. Philadelphia has been outscored 36-0 in the fourth quarter of its last three games, all losses. The team so lauded for its free agency haul after the lockout is in last place in the NFC East.

San Francisco's comeback began after Akers' field-goal attempt was blocked and Henery soon after made a 32-yarder for a 23-3 lead.

Rookie coach Jim Harbaugh then allowed Smith to look downfield more, and the Niners needed just four plays to go 80 yards, including a 44-yard catch and run by rookie Kendall Hunter, who supplemented Gore perfectly. Morgan got wide open over the middle for his TD.

Then Henery began missing kicks after Vick set him up with big plays. Philadelphia had 13 plays of at least 15 yards, including a 61-yard bomb to DeSean Jackson that was wasted when Henery missed from 39 yards.

Davis' touchdown catch brought the Niners within six points late in the third quarter. When Henery failed from 33 yards, it was the final opening the 49ers needed.

Gore had a 21-yard run on the 77-yard drive that ended with his powerful surge into the end zone. He finished with 127 yards rushing.

Jeremy Maclin fumbled with 2:06 left and the Eagles driving for perhaps a winning score.

Vick turned a seeming sack into a sensational touchdown in the first quarter. He was about to go down at the San Francisco 16 when rushed by Ahmad Brooks and Ray McDonald. Both had open shots at him, and both missed. Vick scrambled right and found Clay Harbor in the back right corner of the end zone to make it 7-0.

Henery did make three field goals, from 32, 32 and 33 yards. -- (AP)

The two-time Pro Bowl wide receiver already was tagged as the franchise player, and now gets the long-term contract he wanted. The deal was announced on Wednesday.

Jackson held out last training camp because he wanted an extension and let the contract situation affect him. He was deactivated for a game for being late for a team meeting, dropped more passes than usual and his production dropped. But the Eagles are counting on Jackson to be the dynamic player he was in 2009-10.

Philadelphia stumbled to an 8-8 season last year, but closed with four consecutive victories, building momentum for 2012. The Eagles finished, despite a 4-8 start, just one game behind the New York Giants, who not only won the NFC East, but also the Super Bowl.

"We are thrilled to be able to keep one of the NFL's top playmakers in Philadelphia," Eagles coach Andy Reid said. "DeSean is a game breaker. He has the speed and ability to score from anywhere on the field, and he has proven himself to be a big threat for our offense."

Jackson has career totals of 229 receptions, 4,085 yards and 21 touchdowns in four years as an Eagle after being drafted out of Cal. He also has three rushing scores and a franchise-record four punt return touchdowns, as well.

"Signing our own players was a big priority for us this offseason," Reid said. "And DeSean was certainly high on our list. We are very excited about his future as an Eagle."

Jackson, 25, was named to the Pro Bowl following the 2009 and 2010 seasons, and is one of five players in NFL history to at least 900 yards receiving in each of his four seasons.

Earlier in the day, defensive end Trent Cole and the Eagles agreed on a four-year contract extension through 2017, and on Tuesday, offensive tackle Todd Herremans agreed to a three-year contract extension through 2016.

Cole is a two-time Pro Bowl selection who ranks third on the team's all-time list for sacks with 68. He had 11 sacks in 2011, his fourth season with a double-digit total.

"Trent plays the game with a level of tenacity that's hard to replicate," Reid said. "He's one of the premier defensive ends in the league."

With the key returnees, there's a feeling — inside the organization, at least — that Philadelphia will return to its status as a perennial playoff team in the NFC.

"As the season went on, we started coming together a lot more and it showed by us winning our (last four) games," Herremans said. "We really feel that we don't need any extra pieces brought to us in free agency. We feel that the team we have in the locker room can make a great run and go to the Super Bowl next year." -- (AP)

Time to concede? Not quite. Not against the self-destructive Miami Dolphins.

Vick made a triumphant return from an injury by throwing for 208 yards and a touchdown, and the Eagles totaled nine sacks and beat the Miami Dolphins 26-10 Sunday.

Philadelphia took advantage of three takeaways to score 24 points during a nine-minute span in the second quarter, and later sent Miami quarterback Matt Moore to the sideline with a head injury.

The underachieving Eagles (5-8) won for only the second time in the past six games and still need a sweep of the final three games to have any chance of repeating as NFC East champions.

"We've been through a lot, a lot of games we were supposed to win and didn't finish," Vick said. "I'm proud we won today."

The Dolphins (4-9) had a three-game home winning streak snapped and sank deeper into last place in the AFC East.

"We've been on a roll," receiver Brandon Marshall said. "It stinks that our momentum was stopped."

Jason Babin led the Eagles' pass rush with three sacks to increase his season total to 15, and he forced a fumble. Moore's replacement, J.P. Losman, was sacked by Phillip Hunt for a safety.

Vick, back after missing three games with broken ribs, won for only the fourth time in his past 12 starts. He went 15 for 30, including a 34-yard touchdown pass to DeSean Jackson, and shook off four sacks.

"I'm in a lot of pain, but I just wanted to finish and get through the game," Vick said. "I got hit a lot, and it kind of wore me down. I tried to hang in there."

Vick, who had said he would run less in the wake of the injury, carried only twice but did scramble several times to extend plays. LeSean McCoy rushed for only 38 yards, but scored two touchdowns to hike his season total to 17.

Miami Pro Bowl tackle Jake Long left the game in the first quarter with a back injury, and after that the Dolphins had trouble blocking Philadelphia. The Eagles' short-yardage defense stuffed Miami on four possessions, twice on fourth down and twice to force kicks.

"The Eagles have been inconsistent like we have," Marshall said. "But that's a team with a lot of talent. At any moment they can be an undefeated team, or look like one."

The Dolphins went 3 for 18 on third- and fourth-down conversions. The nine sacks of their QBs equaled a franchise record set in 1999, and the offensive linemen took responsibility for the loss.

"All the blame is squarely on our shoulders," guard Richie Incognito said. "We got Matt hurt. They're a physical group. They just beat us one on one."

Moore threw only his second interception in the past six games, lost a fumble and was sacked four times. He left the game midway through the second half after being hit from behind as he threw an incomplete pass.

Miami's lone touchdown was set up by an early blocked punt. Marshall was held to four catches for 27 yards.

"There comes a time when we as players and coaches have to do a better job of getting guys involved that need to be involved," Marshall said. "It just didn't seem like we had anything on offense in the second half that could attack what they were throwing at us."

The Dolphins' offensive ineptitude negated a lot of good work by their defense. McCoy, who came into the game second in the NFL in rushing, averaged only 1.4 yards on 27 carries. Jason Taylor sacked Vick twice in first eight minutes to increase his career total to 138½, which ranks sixth all time.

Miami's Jimmy Wilson blocked a punt to set up the game's first score, which came when Moore hit Brandon Marshall on third down for a 16-yard score.

A gamble by the Dolphins then backfired when they tried a 55-yard field goal that fell short. Vick took advantage of the field position to drive his team 54 yards for a tying touchdown, which McCoy scored on a 2-yard run.

Turnovers by Miami on consecutive possessions led to 10 points for the Eagles.

Kurt Coleman intercepted Moore's pass when he threw deep into triple coverage, and his return to the 1 set up a touchdown run by McCoy.

On the next series, Asante Samuel forced a fumble by Davone Bess and recovered, and the Eagles kicked a field goal. After Moore lost a fumble when sacked by Babin, the Eagles then moved 73 yards in just four plays, and Vick's strike to a wide-open Jackson made it 24-7.

"We played like men today," Babin said. "Do we have a chance for the playoffs? Maybe. We were kind of out of it, but guys in this locker room decided, 'We're going to play and have fun and show you guys we love the game.' I think that really rang true the whole day."
