The Pittsburgh Steelers made two roster moves today in advance of their Thursday night game vs. the Browns, one expected, the other a surprise.

As expected, the Steelers placed reserve nose tackle Chris Hoke on injured reserve, ending his season and perhaps his career. Hoke suffered a stinger ealier in the year, and has not played since.

The other moved was to place reserve running back Jonathan Dwyer on IR, ending his season as well. Dwyer was injured in the Steelers victory over Cincinnati, and the move comes as a surprise.

To take their roster spots, the Steelers activated linebacker Mortty Ivy and safety Damon Cromartie-Smith. Those moves leave the Steelers with three lone running backs on their roster, Rashard Mendenhall, Isaac Redman, and Mewelde Moore.
