Yes, that was quite a shocking ending. An end to the fight that no one really wanted to see. It would have been nice to see this one go the distance to see if Weidman had it in him to retain the belt. It was pretty obvious Silva was taking this bout a lot more serious than the last between these two. I too thought Weidman almost ended it in the first round.
I feel as though this injury is probably a career ender for Silva. I have broken my tibia/fibula in a similar place as he did, and with surgery to get a tibial nail (stainless rod in my tibia from knee to ankle), it was still a 5 month recovery. If it doesn't end his career, his kicking game will never be the same. An unfortunate injury to sustain.
