During a meeting Tuesday in Las Vegas, the Nevada State Athletic Commission tapped veteran referee Steve Mazzagatti to officiate UFC 156’s main event.

Additionally, the commission named Adelaide Byrd, Jeff Collins and Junichiro Kamijo to judge the featherweight title fight, which pits champ Jose Aldo (21-1 MMA, 3-0 UFC) against ex-lightweight champ Frankie Edgar (14-3-1 MMA, 9-3-1 UFC).

UFC 156 takes place Feb. 2 at Mandalay Bay Events Center in Las Vegas. The event’s five-bout main-card airs live on pay-per-view following prelims on FX and Facebook.

Mazzagatti, who was chosen for the assignment over veteran referees Herb Dean and Yves Lavigne, will earn $1,200 for his work while judges Byrd, Collins and Kamijo will earn $950 each, NSAC Executive Director Keith Kizer said.

Despite being frequently maligned by UFC President Dana White, Mazzagatti has refereed dozens of high-profile bouts in Nevada. Brock Lesnar accused him of botching his fight with Frank Mir at UFC 81 in a formal request he not oversee a title bout with then-champion Randy Couture at UFC 91. The commission installed veteran ref Mario Yamasaki.

Byrd most recently served as a judge at this past month’s UFC 155, where her 30-27 score for Melvin Guillard over Jamie Varner drew the ire of many MMA observers.

Kamijo also served as a judge at the Dec. 29 event, where he gave Jim Miller the nod by a score of 29-28 in a co-main event fight with Joe Lauzon.

Collins worked summer blockbuster UFC 148, where he notably gave a 29-28 score in favor of Forrest Griffin in a co-main event against Tito Ortiz.
