Kenny Bayless, one of the top referees in boxing, has been named to referee the Sept. 14 junior middleweight title fight between Floyd Mayweather Jr. and Saul “Canelo” Alvarez at MGM Grand in Las Vegas (on Showtime pay-per-view).

The three judges will be Dave Moretti, C.J. Ross and Craig Metcalfe.

Interestingly, Bayless was the third man in the ring when Mayweather won a split decision over Oscar De La Hoya in May 2007 at MGM Grand. De La Hoya is Alvarez’s promoter.
