For now, Clausen has won the Bears' backup job, sources told ESPN NFL Insider Adam Schefter.
Palmer was the first quarterback off the bench to replace starter Jay Cutler in Friday night's preseason game against the Seahawks. He went 7 for 10 for 48 yards. Clausen, once he entered the game, was 6 of 9 for 36 yards.
Neither one put any points on the board as the Bears were routed 34-6.
