TV replays showed his foot pointing in the wrong direction and he was eventually taken off on a stretcher, with Broadfoot in obvious distress.
"I'm not too sure what happened," he admitted.
"I just slid in and looked round and his bone was sticking out. We tried to get the physio on to help him because you don't like to see that.
"These things happen and hopefully he makes a fast recovery. I've never seen anything like that so close before.
"You see things like that on television and it's not good but to see it there in front of you, it doesn't look nice and I just hope he recovers quickly."
