AFC North injuries, Week 15: Jermaine Gresham, Kevin Huber go down

During Week 15, no team sustained more injuries to key players than the Cincinnati Bengals.

Against the Pittsburgh Steelers on Sunday night, Cincinnati watched as three players were taken from the field. Outside linebacker James Harrison, making his first trip back to Pittsburgh to face his old team, was concussed in the first quarter.

Punter Kevin Huber then suffered one of the nastiest hits of 2013, breaking his jaw and fracturing a vertebrae. As if that wasn't enough, tight end Jermaine Gresham exited in the second quarter with a hip injury and did not return afterwards. The timetable for all three to return is unclear.

The Steelers only lost outside linebacker LaMarr Woodley on the first series of the game, injuring his calf, per Steelers Depot. Defensive back Ike Taylor and offensive linemen Marcus Gilbert and Kelvin Beachum also went down but returned to action.

In the Baltimore Ravens win on Monday night over the Detroit Lions, quarterback Joe Flacco took a hit by DeAndre Levy. Levy's helmet hit into Flacco's left knee, causing him obvious discomfort. However, Flacco remained in the game and finished.
