According to Jason La Canfora of the NFL, he stated in his Twitter account earlier this morning that a source within the Seahawks released information on WR Mike Williams with the statement below,
"Seahawks expect Mike Williams will miss a game or more. Situation is "not good" says team source. Not an IR issue, but may be out few weeks".
This isn't good news for the Hawks when they go on the road against the 49ers next Sunday. Good news is that WR Ben Obamanu just has a deep cut on his left hand and will be ready to play. With the possible return of DT Colin Cole to help out the run game, the Seahawks will need to pull a win off in San Francisco in order for anyone to believe they deserve the division.
(Update): Coach Pete Carroll just announced in his press conference that Mike Williams has a sprained ankle and HAS NOT been ruled out yet of the 49ers game.
