UFC light heavyweight champion Jon Jones successfully defended his title for the fifth time tonight at UFC 152 against Vitor Belfort, but it wasn't easy. Belfort locked up a tight armbar in the first round, and both fighters said at the post-fight press conference that the arm was starting to pop. Jones showed up at the press conference in a sling and said that he wasn't 100% sure of the extent of the injury yet:
"We haven't been able to get my arm x-rayed yet, but they're saying there might be some nerve damage in the bicep."
Belfort stated that when he felt the arm start to pop a bit, he might have released his grip a bit because of that. No matter what happened, Jones was able to escape the armbar and continue fighting, even though he said that his arm went numb right afterwards. He also stated that he tried to throw punches with it later in the fight, but he didn't have any power on his strikes.
UFC president Dana White said he has no idea what's next for Jones, and would need to find out the severity of the injury before he came up with anything.
