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.

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.

Terence Crawford confronted the victor in the ring, and that brought the announcement he and Álvarez will face off on Sept. 12 in Las Vegas: This battle is a long time coming given Crawford and Canelo's respective places within the sport. Bleacher Report's Lyle Fitzsimmons ranked them as the No. 3 and 6 pound-for-pound boxers in the world.
