Pittsburgh Steelers' Ben Roethlisberger says he is day-to-day

Pittsburgh Steelers quarterback Ben Roethlisberger said on Sunday that his right shoulder is sore and termed his status for next Sunday's playoff game against the Denver Broncos as day-to-day.

Roethlisberger, who spoke briefly to reporters, said he had an MRI on Sunday, but did not know the results. He is still uncertain how severe the injury is and won't have a clear picture of the damage until he meets with doctors later in the week.

Roethlisberger was injured in the second half of Saturday's 18-16 victory over Cincinnati when he was sacked by Bengals linebacker Vontaze Burfict. Roethlisberger landed on his right shoulder.

The team initially believed Roethlisberger suffered a sprained AC joint in his right shoulder.

Roethlisberger left the field after his injury, but returned to the sidelined and sat out the Steelers' next few offensive possessions.

He re-entered the game with 1:23 remaining in the fourth quarter and led the Steelers on a nine-play, 74-yard drive -- aided by two 15-yard penalties on the Bengals -- that ended with Chris Boswell 35-yard field goal to win the game.

Roethlisberger said Sunday he was in "a lot" of pain on the final drive, and told coaches he would have trouble throwing farther than 10 yards.
