Pittsburgh running back Ray Graham injured his right leg making a cut out of the backfield. Graham grabbed his knee instantly as he made his cut, going right to the ground without an contact. He had to be carried off the field by his teammates and was visibly in pain. It was just Graham's second carry of the game following an 18-yard run. It looks like a serious injury, as Graham was swarmed by trainers on the sideline. When news of the specific injury is available, we will update you. Graham was carted from the sideline to the locker room, so it looks like he will be out for the rest of the game.

Junior running back Zach Brown replaced Graham after the injury. Brown is a transfer from Wisconsin who was available to play right away because of graduation rules. Brown is a much bigger running back and has seen just limited time during the 2011 season.
