The Bengals signed University of Cincinnati product J.K. Schaffer off the practice squad, adding the linebacker to the 53-man roster. The undrafted second-year player officially took a spot vacated by safety Jeromy Miles. A fourth-year player himself, Miles had been battling a hamstring injury and was limited in practices this week. He was listed as doubtful on Saturday's injury report and was waived by the team Monday.
Miles appeared in 39 games for the Bengals since 2010. His lone start in Cincinnati came last season. He had 12 total tackles and a pass deflection in his time with the Bengals.
Schaffer has not yet played in a regular-season game, but the local product became a fan favorite in the preseason. With appearances in all four games, he had a combined 20 tackles, recorded a sack and an interception.
The Bengals and Steelers meet at Paul Brown Stadium at 8:30 p.m. ET (ESPN). Both enter the AFC North clash with 0-1 records.
