Former UFC interim heavyweight champion Shane Carwin was unsure if he would ever be able to compete inside the Octagon again after undergoing back surgery.

Now, as Carwin posted on his own personal website recently, he will be able to fight once again, and is targeting a return to action this year.

“I informed UFC Matchmaker (Joe Silva) that I would like to fight in early fall 2012,” Carwin posted. “I would like to be able to fight every three or four months. Barring injury I intend to leave the UFC octagon and head back to the Grudge Training Center to continue the climb.”

Carwin put together several first round knockouts to garner a match with Frank Mir for the interim UFC title. Carwin (12-2) won that bout, but was unable to unify the title against Brock Lesnar.

Carwin last fought at UFC 131, falling to Junior dos Santos after replacing Lesnar in a match to determine a No. 1 contender. He cited injuries in football as a main reason for the recent back surgery.
