Chris Hoke, Jonathan Dwyer on IR

PITTSBURGH -- The Pittsburgh Steelers have placed nose tackle Chris Hoke and running back Jonathan Dwyer on injured reserve.

Hoke hasn't played since injuring his neck against Jacksonville on Oct. 16. The 35-year-old will need surgery and there's a chance his career is over. He's become a valuable backup during his career and the Steelers are 17-1 when he starts, including a 2-0 mark this season.

Dwyer will miss the rest of the season with a left foot injury. He rushed for 123 yards this season, including a 107-yard effort against the Jaguars.

The Steelers placed linebacker Mortty Ivy and safety Damon Cromartie-Smith on the 53-man roster to replace Hoke and Dwyer.
