Steelers QB Ben Roethlisberger left Pittsburgh's 27-24 loss at Kansas City on Sunday with what head coach Mike Tomlin called a "concussion-oriented" injury. Roethlisberger suffered the injury when hit while scrambling in overtime.

Roethlisberger was replaced by Charlie Batch, who completed 1-of-2 passes for 17 yards. Roethlisberger completed 32-of-42 passes for 398 yards with three TDs and two interceptions before departing.

The Steelers (6-4) play a pivotal game at 5-5 Baltimore next Sunday.
