The Columbus Dispatches' Bill Rabinowitz reports that Rich Braham "has a fracture in his left leg, at the top of his tibia just below his knee".
To me, this makes more sense. I guess when he was carted off, I was a little surprised that the injury was just a deep bone bruise. Admittedly, I've never had a deep bone bruise on my knee. But it doesn't seem like an injury that tough Rich Braham would require a cart to leave the field of play.
