UFC president Dana White has been forced to make an historic decision. For the first time in 11 years, White cancelled an event -- UFC 151 -- after Dan Henderson was forced to withdraw from a main event light heavyweight bout with champion Jon Jones.

Rumors of Henderson's possible withdrawal due to a partial MCL tear began circulating yesterday.

From MMA Mania:

After several unsuccessful attempts to secure a new opponent for Jones, the UFC unfortunately made the unprecedented move of canceling UFC 151 altogether. “This is probably one of my all time lows as being president of the UFC,” said White. “For the first time in 11 years, we’re going to cancel an event. Dan Henderson has a partial tear in his MCL (and could not continue).”
