PITTSBURGH (AP) — The Pittsburgh Steelers escaped with a victory. The health of their franchise quarterback is another matter entirely.

The Steelers edged the woeful Kansas City Chiefs 16-13 in overtime on Monday night but lost Ben Roethlisberger for most of the second half — and perhaps a lot longer — with a right shoulder injury.

Roethlisberger left early in the third quarter after getting slammed to the turf by Kansas City linebackers Tamba Hali and Justin Houston. Coach Mike Tomlin said he was taken to a hospital for evaluation.
