The Bucs plan to place quarterback Chris Simms on injured reserve, general manager Bruce Allen said Tuesday.

"We're going to put Chris Simms on injured reserve tomorrow,'' Allen said during a conference call on Tuesday. "This what we feel is the best move for Chris to regain his full strength. We've been very hopeful, as has Chris, that his recovery from from the splenectomy, that he would've recovered by now. It's just taking longer than both Chris and we had hoped for. We'll make another roster move to add a player (Wednesday).''

The Bucs plan to use Simms' roster spot for a running back following severe injuries in consecutive weeks to Cadillac Williams and Michael Pittman. Williams was placed on injured reserve and Pittman will miss 6-8 weeks with a high ankle sprain.

Allen said the Bucs are likely to select from a list of four running backs the team worked out Tuesday.

Although Allen wouldn't reveal the list, those running backs were Pittsburgh's Kevan Barlow, Florida's Ciatrick Fason, Alabama's Shaud Williams and Notre Dame's Tony Fisher. Last week, the Bucs worked out former Florida State fullback Zack Crockett, who played for Jon Gruden with the Raiders.
