(Marc Serota/Getty Images)Pittsburgh Steelers backup quarterback Charlie Batch injured his left wrist after replacing Ben Roethlisberger during an overtime loss in Kansas City and could miss the rest of the regular season.
Batch was hurt despite taking part in only four plays in the Steelers' 27-24 loss — his first game action since 2007.
He is expected to undergo surgery later this week to repair the wrist; he is expected to miss approximately six weeks. Batch sat out last season with a broken collarbone.
Roethlisberger left with concussion-like symptoms when his head struck Chiefs linebacker Derrick Johnson's knee while he was being dropped for a one-yard loss in overtime. Roethlisberger was examined Monday and his status for Sunday night's game in Baltimore is uncertain.
Dennis Dixon is the Steelers' No. 3 quarterback, but hasn't played this season and has appeared in only one NFL game.
