Canelo Alvarez was recently spotted sparring Jaron Ennis to prepare for his fight against Terence Crawford. Canelo vs Crawford goes down at Allegiant Stadium in Las Vegas on September 13.

The veteran referee will be the third man in the ring when Saul "Canelo" Alvarez and Terence "Bud" Crawford battle for Alvarez's undisputed super middleweight title on the Sept. 13 Netflix-streamed show at Allegiant Stadium in Las Vegas, Nevada.

Crawford claimed the WBA junior middleweight title in a twelve-round, unanimous decision victory over then-unbeaten Israil Madrimov last August 3 in Los Angeles, California. The distance win snapped Crawford’s 11-fight knockout streak, though it still resulted in his tenth major title collected over four weight divisions.
