Floyd Mayweather and Robert Guerrero will have veteran referee Robert Byrd sharing the ring with them on May 4 in Las Vegas, and the Nevada commission also selected the judges today, naming Jerry Roth, Duane Ford, and Julie Lederman as the official judges for the bout.

Byrd is a fine choice as referee, a quality pro who stands out as one of the more consistent and reliable officials in the sport. He has never refereed a Mayweather fight before. Recent big fights for Byrd have been Pacquiao-Bradley, Vazquez-Gesta, and Huck-Afolabi II in Germany.

Roth and Ford are well-known, and not for great reasons. Lederman is a fine judge and a good choice, but Roth and Ford are a bit worrisome, even though historically, Mayweather fights are pretty easy to score. It's worrisome simply because they aren't particularly good judges anymore. The sport is dying for some turnover at the top levels with officials.

Jay Nady will referee the main undercard bout between Daniel Ponce De Leon and Abner Mares, with Dick Houck, Robert Hoyle, and Michael Pernick assigned as judges.
