Montario Hardesty tore a calf muscle in Sunday's loss at San Francisco, leaving the Browns with just one healthy running back on its current roster. Cleveland coach Pat Shurmur said Hardesty will be out an indefinite period. "It will be games," said Shurmur, adding Hardesty is wearing a protective boot. "It will take him a little time to heal up from this injury. I can't tell you how many (games)." Hardesty, who missed his rookie season following knee surgery and was starting because Peyton Hillis is injured, was injured on Cleveland's second series. The Browns (3-4) will bring in running backs for tryouts Tuesday at the team's training facility.
