Why Seattle named Mike Williams inactive

SAN FRANCISCO -- Top receiver Mike Williams moved fairly well during warm-ups Sunday.

Williams' foot and ankle injuries threatened his ability to play a full game, however, and the Seattle Seahawks felt they could not commit a roster spot to him against San Francisco, particularly after Williams did not practice all week.

Williams does not play special teams, another consideration.

Keeping Williams active as a luxury would have required paring the roster elsewhere. The team did not feel comfortable sitting down one of its eight active defensive linemen.

The team needed to guard against depth issues on the defensive line in case nose tackle Colin Cole suffered another injury. Cole is coming back from an ankle injury and well ahead of Williams in the recovery process. He practiced all week.

Seattle kept eight defensive linemen active Sunday: ends Chris Clemons, Raheem Brock, Dexter Davis and Kentwan Balmer, plus tackles Brandon Mebane, Cole, Junior Siavii and Craig Terrill.

I would expect Williams to start against Atlanta in Week 15.
