Shane Carwin's manager, Jason Genet of Ingrained Media, told Fighters.com on Wednesday night that his client suffered extensive damage to his knee in training. UFC president Dana White confirmed that Carwin will not make his scheduled December encounter with Roy Nelson at The Ultimate Fighter 16 Finale.
"He was essentially training through the injury and pushed too hard, too fast," Genet said. "The gut feeling is that he can recover without surgery if he rehabs it."
Genet said that Carwin, a former interim UFC heavyweight champion, tore his PCL, LCL and popliteus in his knee, but added, "Shane will be fine and is staying positive."
Carwin has not competed since early in 2011, falling to current UFC heavyweight champion Junior dos Santos. He underwent back surgery and was on his way to returning before the knee injury.LINK
