Marshawn Lynch, a franchise icon and a fan favorite who established himself as one of the best running backs in franchise history during his six seasons with the Seahawks, could be re-signing with his former team soon.

The Seahawks lost running backs Chris Carson and C.J. Prosise to season-ending injuries in Sunday's loss to Arizona, and a day later head coach Pete Carroll said on 710 ESPN Seattle that Lynch is on his way to Seattle for a physical, and if all goes well, he could be on the field when the Seahawks host the 49ers in a game that will decide the NFC West title.

"He'll be flying in here this morning, and we're going to give him a really good chance to come back and play for us," Carroll told the Danny and Gallant show. "I'm fired up for it. He's got to get through some hoops he's got to jump through, just a physical and stuff like that. But he has been working really hard, he's really excited about the chance to do something helping out, and I think it's freakin' great if he can get out there and tote the ball for us. The circumstances rolled just at this time, and he could have four or five games left in him, maybe that's what we need."

The Seahawks already lost Rashaad Penny to a season-ending injury in Week 14, so the general manager John Schneider had already been considering his options at running back, and with Carson and Prosise both out, now was the time to bring Lynch in, Carroll said.

"John is always on the options, and in astute fashion, he has been connected with this one just in case for a long enough time that we've had some runway for it," Carroll said. "(Lynch) has had plenty of time to be working and get ready in case something came up, and I'm anxious to see him when we get him here."

Lynch, who spent the last two seasons playing for his hometown Oakland Raiders—his last game was against the Seahawks in London last year—wasn't just a four-time Pro-Bowler who rushed for 6,347 yards and 57 touchdowns in Seattle, he was a tone-setter who helped define that era of Seahawks football.

"There's a lot of history here that's great history," Carroll said. "There was nobody that ever amplified the kind of mentality and toughness that we like to play with. So if we get a chance to get the Beast back on the field, we'll see how that works out."

Nothing is final yet. As Carroll noted, "what we understand is he's in really good shape, but we need to get him here, then away we go. We'll keep our fingers crossed that it works out… We'll let you know in a few hours here."
