Willson (knee) may require surgery, SeattlePi.com reports. "We've got to figure out what to do with him. Got a little cartilage damage in there and stretched ligaments and MCL, so we've got to figure out what that's going to be like," said head coach Pete Carroll.

Willson went down blocking for a Christine Michael touchdown run in the fourth quarter and did not return. If he's ruled out for an extended period of time, Seattle will likely turn to either Brandon Williams or Nick Vannett to fill Willson's role as the team's primary blocking tight end.
