Roethlisberger was sacked by Justin Houston to end Pittsburgh's first possession of the second half. The quarterback was taken to the locker room after walking off the field and backup Byron Leftwich began warming up. Roethlisberger was 9 of 18 for 84 yards and a touchdown at the time of the injury.
Roethlisberger has been largely injury-free this season in offensive coordinator Todd Haley's system, which requires him to get rid of the ball quickly. Kansas City's secondary, however, shut down Pittsburgh's receivers and Roethlisberger took a series of hits on a wet night at Heinz Field.
