Buck Pineau entered the fight with two healthy and functioning arms. He left the cage with one. (WARNING: Video is graphic)
Today is Halloween, which means you'll see all sorts of scary things, real or fake, whether you like it or not. This video from last night's CES 31 event in Rhode Island is very real and quite brutal.
Buck Pineau was just trying to lessen the impact from an attempted slam by opponent Pat McCrohan, so he instinctively put his left arm to help brace his impending big fall. Unfortunately his arm shattered, and he was tapping seconds later due to the intense pain.
