Pittsburgh signed former Ohio State center Alex Stepanovich to add depth to its offensive line. The Steelers recently lost guard and backup center Darnell Stapleton to knee surgery. To make room on the roster, Pittsburgh released defensive lineman Jordan Reffett.
The Bengals also terminated the contracts of two running backs in Kenny Watson and fullback J.D. Runnels. Watson was a solid contributor for the Bengals in previous years, but recent injuries for Watson and new additions to the position in the offseason made him expendable in Cincinnati.
