Steelers' Redman scheduled for MRI

LATROBE, Pa. -- Running back used to be one of the Steelers' deepest positions. Now, it's become one of their chief concerns.

The latest injury question mark at running back is Isaac Redman, who said he will get an MRI on Thursday morning. He has been limited by a groin injury that has become worse since the start of training camp.

"It hurts a little," Redman said. "It's tough to run right now."

Redman's situation has left the Steelers extremely short-handed at running back, where three players have gone down with injuries. Rashard Mendenhall, the Steelers' starter, is expected to start the season on the Physically Unable to Perform (PUP) list after ACL surgery in January. Reserve back John Clay suffered a season-ending thigh injury. And Jonathan Dwyer, Redman's backup, is dealing with a sprained shoulder.

The only healthy running backs are rookie Chris Rainey and Baron Batch.

Redman doesn't think the groin injury will linger into the regular season. "I heal pretty fast," he said.

Apparently no one told offensive coordinator Todd Haley the latest development with Redman.

"I don't know anything about that. I heard he was practicing today," said Haley, who spoke to reporters about an hour after Redman. "He was a little nicked up but we've been a little short at that position. So, coach is overall trying to be real smart especially the spots where we're a little short."

When asked again about Redman's injury, Haley said, "You guys have more information than I do right now. We're not trying to put too much on him because he is a little bit nicked up. But the way I understood it, we're going to stay on course with the plan to get him some carries in this game."

The Steelers play the Colts in their second preseason game Sunday.
