Here is an article on this. Word was orginally that Troy Vincent railed him but Vincent explained himself in this article.

Rookie quarterback J.P. Losman has suffered a broken leg and will be out indefinitely. Such injuries typically require a recovery time of 8-12 weeks.
Losman went down during 11-on-11 action with 25 minutes left in practice and was helped into a cart and driven off to the locker room.
The first-round draft pick was injured when he made contact with cornerback Troy Vincent while he was finishing up a run to the right side during a two-minute drill. He got up immediately and started limping before falling back to the ground, where team trainers attended to him for about five minutes before he was carted off the field.
"I was running and keeping him from going out of bounds and he was cutting back and our shoulder pads just barely grazed on his cutback," said Vincent. "At the same time he was planted I think our shoulder pads met."
"I don't think anything was intentional," Mularkey said. "I think it was accident out on the field. Troy is not going to hurt anybody and J.P. loosened up at the end. You can't do that."
After noticing Losman was still down, Vincent went over to check on him.
"I had finished the play and I hadn't realized that he had fallen," Vincent said. "He had said that he caught the edge of my shoulder pads on my cutback and he had got twisted up on the ground. I just wanted to make sure he was ok."
Losman, the second of the team's two first-round draft picks, has been guilty of taking unnecessary hits from defenders as opposed to sliding to avoid the hit.
"He's an aggressive guy," said Vincent. "Over time with maturity he'll learn. J.P. plays on edge and he'll learn to slide. In this particular practice today it wasn't a live drill. It was a two-minute situation and the last people we want to hit are the quarterbacks. We know red jerseys are not allowed."
A two-time captain who set the Tulane career record for lowest interception percentage in school history, Losman was the first quarterback taken in the first round by the Bills since Jim Kelly was drafted with the 14th pick in 1983.
Notes: Starting offensive tackle Jonas Jennings left practice early after sustaining an ankle injury during a linemen drill. Wide receiver Eric Moulds was given day off to recover from a chest injury that occurred during Saturday's Titans game. Punter Brian Moorman returned to practice for the first time in nearly a week. Starting running back Travis Henry missed his second straight practice with bruised ribs. Cornerback Terrence McGee, safety Mark Graham (hamstring), and offensive lineman Marcus Price (foot) also did not practice.
