The Bengals put wide receiver Andre Caldwell on season ending injured reserve.
Caldwell, who caught a touchdown in Cincinnati's win at Baltimore this season, did not play against St. Louis or Arizona with a groin injury.
The Bengals signed former UC Bearcat Armon Binns to the active roster to replace Caldwell. The team also worked out and signed another former UC receiver, Vidal Hazelton, to the practice squad.
