The Bears announced that rookie running back Harvey Unga has been placed on injured reserve.
Unga has missed most of training camp after suffering a hamstring injury. Selected with a seventh-round pick in the NFL's Supplemental Draft, the Bears were intrigued by Unga's size and potential as a hybrid fullback.
Unga will count toward the 80-man roster until the team is required to cut down the roster to 75 players on Aug. 31.
The Bears have been pleased with the play of Kahlil Bell behind veterans Chester Taylor and Matt Forte. Garrett Wolfe is also in the mix.
