After seven games of stability along the offensive line, the San Francisco 49ers were forced to move things around in Week 14 against the New York Jets.
Joe Staley (hamstring) missed his first game since 2010. Zane Beadles was tasked with playing left tackle while Marcus Martin stepped in at left guard. When Daniel Kilgore (hamstring) went down in the first quarter, Martin moved to center with Andrew Tiller entering the game at left guard.
Staley is officially listed as doubtful and is unlikely to play on Sunday.
