Shane Carwin has admitted he lied to the doctor in order to avoid being stopped in UFC 131's main event.

Carwin suffered a beating from Junior Dos Santos in Saturday's heavyweight showdown, receiving heavy cuts around his eyes as well as a busted nose. He fought to the final bell though, despite a third-round pause for a medical check.

Referee Herb Dean became concerned about one particular cut around Carwin's eye, and the heavyweight admits he could not see for the final five minutes.

A doctor was clearly seen asking Carwin if, when looking directly ahead, he could see the medic's hand out the corner of his eye. Carwin convincingly replied 'Yes', but he admits the truth was rather different.

"After the second round I knew I was in trouble," the American was quoted as saying by USA Today. "My nose made it impossible to breathe, my eyes were full of blood and Junior was still coming at me. When the ref stopped the fight in the third, I thought it was over.

"When the doctor came in the Octagon I knew it was going to be up to me to sell them on letting me continue. I knew I was in deep trouble but I also knew that all I needed was one clean shot.

"I wanted to keep myself in the fight. I wasn't able to see but I said I could and we continued."
