Today Gilberto Faria, manager of UFC middleweight Ronaldo ‘Jacare’ Souza revealed that the fighter had recently undergone surgery to remove bone fragments from his elbow. The injury occurred prior to the fight and was a hindrance during his fight camp:
Souza, the No. 4 ranked UFC middleweight who recently defeated Francis Carmont via unanimous decision, suffered the injury several months prior to UFC Fight Night 36. According to his manager Gilberto Faria, Souza was unable to work out anything but his legs throughout the first two months of his three-month pre-fight camp for Carmont.
“I didn’t have trouble (in the fight) because of the injury,” Souza said at UFC Fight Night 36’s post-fight press conference. “I have bone fragments in my left arm and I almost pulled out of the fight, but I asked the UFC to continue. I asked my doctors if I could fight and they said there was a high possibility that I could fight.”
At first read, the surgery doesn’t sound too serious, but as you can see by photos released exclusively to MMAFighting, there was a serious amount of damage removed from the elbow of Souza:
