PITTSBURGH -- Pittsburgh running back Ray Graham has left Wednesday night's game against Connecticut with a leg injury.
Graham, the Big East's leading rusher, had to be helped off the field by trainers after running for a short gain on Pitt's first possession.
Graham clutched his right knee as he laid on the Heinz Field turf then punched an equipment table as trainers tended to him on the sideline. He was quickly taken off the field on a cart.
Graham returned to the field in street clothes and is expected to have an MRI on Thursday to determine the extent of the injury.
The junior has been one of the few bright spots for the Panthers. He came in averaging 134.1 rushing yards per game, tops in the conference and second in the country. He was replaced by Zach Brown.
