Carwin (12-2) has not stepped in the cage since UFC 131 last year, which was a lost against Junior dos Santos by decision. The former interim heavyweight champion recently told “Inside MMA” on AXS TV that he was working is way through a knee injury he suffered in training.
With Carwin out, the UFC will search for a replacement for Nelson and a new opponent should be announced in the next couple of days.
