Concerned that C Max Unger’s strained right foot won’t be ready Sunday, the Seahawks signed Patrick Lewis to the 53-man roster Wednesday to add depth behind Stephen Schilling, the only other center on the roster other than long snapper Clint Gresham.
Coach Pete Carroll said Unger is day to day. He left the game in Washington Monday night for three plays, then returned. He was in the locker room without a boot Wednesday.
To make room for Lewis, the team waived CB Josh Thomas, signed following the first game of the season.
Lewis, who was with Seattle briefly for the preseason game against Oakland, was the center at Texas A&M when Johnny Manziel won the Heisman. Most recently, he was on Cleveland’s practice squad.
