With center Max Unger day-to-day with a foot sprain, the Seahawks decided to bolster their depth at center by signing Patrick Lewis off of Cleveland's practice squad. Lewis was with the Seahawks in training camp and preseason and had previously been with the Jaguars and Packers.
Unger left the game for a part of one series on Monday after spraining his foot, but was able to return to the game on the next drive. This move is likely just a precaution, because if Unger can't go on Sunday vs. the Cowboys, Seattle would only have one center on the roster in Stephen Schilling. Schilling got three snaps Monday in relief, and his first snap was to Russell Wilson in the shotgun, and went really low. There was a delay of game on his second "snap", then a one-yard rush by Robert Turbin on his third. His final snap was the pass to Marshawn Lynch out of the backfield that went for 9 yards and a touchdown.
The Hawks released cornerback Josh Thomas in a corresponding roster move.
