The mega-fight between undisputed super middleweight champion Canelo Alvarez and unbeaten four-division champion Terence Crawford has moved from Friday, Sept. 12, to Saturday, Sept. 13.

Terence Crawford and Saul "Canelo" Alvarez will be going head-to-head with UFC for their September showdown — abruptly throwing TKO's involvement with the fight into question.

Mere moments after Canelo Alvarez won his May 3 fight against William Scull, pound-for-pound great Terence Crawford entered the ring to face off with him. This finalized what has been the worst-kept secret in the boxing world over the past few months: That Canelo and Crawford are going to fight later this year.
