The Pittsburgh Steelers suffered an injury to one of their running backs on Sunday as Bob Labriola reports via Twitter that second year running back John Clay has been taken off on a cart after suffering an unspecified injury.
The Steelers were already thin at the running back position heading into the Sunday practice as both Isaac Redman (groin) and Jonathan Dwyer (shoulder) were both held out of practice with minor injuries. In addition, Rashard Mendenhall (knee) remains limited to working on the side with trainers as he is still on the PUP list, and will remain there to start the regular season.
With Clay going down injured, that leaves the Steelers with only Baron Batch and Chris Rainey as the two healthy running backs currently on the roster along with fullback Will Johnson. The Steelers also lost starting fullback David Johnson (knee) to a torn ACL and MCL this past Thursday in their first preseason game of the 2012 season against the Philadelphia Eagles.
Labriola did add via Twitter that the injury suffered by Clay was not to his knee
UPDATE: Mike Tomlin said after practice that the injury to Clay is a groin or a hip. He will be evaluated, but was in a lot of pain.
