A fresh start for Marshawn Lynch (Oakland Tech/Cal). A rugged runner for Seattle's lagging ground game.

And a clear sign the rebuilding continues in Buffalo.

The Bills gave up on Lynch as their featured ball carrier on Tuesday, trading him to Seattle for a pair of undisclosed draft picks. That clears the way to give more playing time for Fred Jackson and first-round draft pick C.J. Spiller in the Buffalo backfield.

And Seattle hopes Lynch provides a spark missing from its run game through the first four weeks.

Seattle released running back Julius Jones, its leading rusher the past two seasons, to clear a roster spot for Lynch.

Without a clear No. 1 back, the Seahawks ran by committee before settling on the speedy Justin Forsett as the featured back the past two weeks. Now Forsett and Lynch -- teammates at Cal -- are reunited in Seattle.

Moss trade?: A league source says the Patriots and Vikings are discussing a trade that would bring star receiver Randy Moss back to Minnesota. The person spoke to The Associated Press on condition of anonymity because he was not authorized to speak publicly about the negotiations. The seven-time Pro Bowler was a first-round draft pick of the Vikings in 1998. He was traded to the Raiders in 2005 and languished for two years before being revitalized in New England.

49ers: The team promoted linebacker Keaton Kristick to the active roster from the practice squad and also named Chris Beake offensive assistant coach.

Redskins: Clinton Portis doesn't think his injured groin will allow him to play in the Redskins' game this week against the Green Bay Packers. Portis told 106.7 The Fan that he's awaiting the results of an MRI on his left groin, which he injured in Sunday's 17-12 win over Philadelphia.

Dolphins: Only 12 hours after a calamitous performance against the Patriots, the Dolphins fired special teams coordinator John Bonamego. Special teams cost Miami 21 points in a 41-14 loss Monday night.

Colts: Team officials announced that safety Melvin Bullitt, Bob Sanders' replacement, will miss the rest of the season with a right shoulder injury.

Panthers: The team released receiver Dwayne Jarrett, hours after his second arrest on a charge of driving while impaired in less than three years.

Jaguars: The team released veteran Todd Bouman, leaving Stanford product Trent Edwards as the only quarterback behind David Garrard.
