Marshawn Lynch

Seahawks running back Marshawn Lynch traveled to Philadelphia on Monday to see a specialist about his abdomen injury, and it’s possible that he will have surgery before returning to Seattle, coach Pete Carroll said.

"I don’t know that about the surgery," Carroll said. "It could happen. I don’t know that. It’s a possibility. But it was to go back there for the evaluation to find out what’s next, and there are a couple choices possibly depending on what the doc feels is necessary, and then we’ll just wait and see what that all means."

If Lynch were to undergo sports hernia surgery, he likely would be out for an extended period of time.

Carroll was asked whether there’s any scenario where Lynch would be back for Sunday’s game against the Pittsburgh Steelers.

"I don’t know about that now," he said. "It’s legitimately bothering him. He would have played yesterday if he could have, so I don’t know that."

Lynch suffered the injury in practice before the Seahawks’ Week 10 game against the Arizona Cardinals. He started and played 79 percent of the team’s snaps. But Carroll said the injury started to bother him late in the game. Thomas Rawls is a must-get if still on wires. It's a fluid situation right now, but it's very possibly Lynch is going to miss some time with this injury.
