CLEVELAND - Cleveland Browns running back Montario Hardesty has a torn calf muscle and is expected to miss some games.
Hardesty, who missed his rookie season following knee surgery, got hurt on Cleveland's second series in Sunday's 20-10 loss to San Francisco.
Coach Pat Shurmur said Hardesty is wearing a protective boot. Shurmur does not know how long Hardesty will be sidelined. The second-year back was starting because Peyton Hillis missed his second straight game with a hamstring injury.
With Hillis and Hardesty out, Chris Ogbonnaya had 11 carries Sunday. He's only been with the Browns for two weeks after being signed off Houston's practice squad.
Shurmur said the Browns will work out running backs on Tuesday. Hardesty is the third Browns running back to sustain a serious injury. Brandon Jackson suffered a season-ending toe injury in the exhibition season.
