Defensive tackle Michael Pierce suffered an ankle injury in Cincinnati and did not return. However, X-rays during the game delivered good news.
"X-rays came up negative, so that's positive," Head Coach John Harbaugh said. "We'll just have to see how it responds tomorrow."
The stout run-stopping lineman seemed to start having trouble in the first quarter and went to the trainer's table early in the game. He returned to action, but was pulled out at halftime and ruled as doubtful to return.
Pierce is a crucial part of the middle of the Ravens' defense alongside Brandon Williams. Pierce has started all nine games and made 21 tackles.
Baltimore had some trouble stopping the Bengals' run game without Pierce consistently on the field, and an extended absence would be a big loss.
Cincinnati entered the game averaging a league-low 59.5 rushing yards per game, but rumbled for 157 yards on Sunday. It was on 40 attempts, however, so only 3.9 yards per attempt. Bengals running back Joe Mixon had 30 carries for 114 yards.
