UFC heavyweight Shane Carwin

By FCF Staff

After being sidelined with injuries and having not fought since June, 2011, former UFC interim heavyweight champ Shane Carwin has announced he’s retiring from MMA.

The 38 year-old fighter made the announcement via his official Twitter account:

Officially retired 2day:-) thank you to my family, friends and fans! #dreambig GOD BLESS!!!

The powerful fighter and former collegiate wrestler hasn’t fought since he dropped a unanimous decision loss to Junior dos Santos at UFC 131. Prior to that Carwin was submitted by former champ Brock Lesnar, who tapped out the Colorado fighter with a second round, arm-triangle-choke at UFC 116 in 2010.

Carwin is likely best remembered for his first round KO win over Frank Mir at UFC 111, as well as his stoppage win over Gabriel Gonzaga at UFC 96 in 2009.

More recently Carwin coached opposite Roy Nelson in the twelfth season of “The Ultimate Fighter”, but a knee injury prevented the heavyweight from fighting Nelson after the show concluded.

After turning pro in 20005, Carwin finishes his career having gone 12-2.
