UFC Light Heavyweight champion Jon “Bones” Jones appeared at the UFC 152 post-fight press conference sporting a sling and a soft cast on his hand thanks to the arm bar that Vitor Belfort locked in the first round.

Belfort was about to make a huge upset and walk out of the Octagon as the new champion but the reigning champ managed to find a way out, but not without consequences.

Jones kept his right arm close to him during the rest of the fight, using his kicks and left arm in his offense. After finishing Belfort with a submission in the fourth round, Jones told Joe Rogan during the interview that he heard his arm pop, but was not going to tap out.

“We haven’t been able to get it X-rayed, but they think there might be some nerve damage in the bicep, but I don’t know,” Jones said during the post-fight press conference.

The extent of the damage remains unknown and the champ will have it checked once he flies back home.
