PITTSBURGH — Steelers quarterback Ben Roethlisberger did not stay in a hospital overnight after receiving a concussion Sunday against Cleveland, but it was uncertain if he will practice this week.

Roethlisberger lay on the ground for nearly 15 minutes after being leveled by two Browns defenders and was strapped to a stretcher as he was carried off the field. He was taken by ambulance to a hospital but left after tests were concluded.

With a week off before they begin practicing for their Jan. 11 divisional playoff game, the Steelers will work out today, Wednesday and Thursday, then take the weekend off. The Steelers expect Roethlisberger to be ready for that game but probably won't rush him back to practice with so much time off before they play again.
