PITTSBURGH (AP) - Pittsburgh Steelers quarterback Byron Leftwich injured his ribs in Sunday night's loss to Baltimore and will not start next week against the Cleveland Browns.

A person familiar with the injury told The Associated Press that Leftwich was hurt during the first quarter of the 13-10 loss to the Ravens. The person spoke on condition of anonymity because the team had not officially commented on Leftwich's status.

The Pittsburgh Post-Gazette first reported the decision.

Leftwich finished the game, completing 18 of 39 passes for 201 yards and an interception. He was sacked three times.

The Steelers (6-4) will likely turn to 37-year-old backup Charlie Batch against the Browns (2-8). Batch is 5-2 while as a substitute starter over the last decade.

The Steelers are already without starting quarterback Ben Roethlisberger, who is out indefinitely with shoulder and rib injuries.
