Kenny Bayless, who has worked dozens of title fights and is widely considered one of the best referees in the world, was appointed Wednesday to work the biggest fight of the year.

At the Nevada State Athletic Commission's monthly meeting, Bayless was assigned to referee the junior middleweight unification fight between Floyd Mayweather Jr. and Saul "Canelo" Alvarez on Sept. 14 (Showtime PPV) at the MGM Grand in Las Vegas.
