The UFC will close out its 2019 pay-per-view schedule next month with UFC 245, which features three championship fights.

The Nevada Athletic Commission has assigned judges and referees for those title bouts, which top the Dec. 14 card at T-Mobile Arena in Las Vegas. NAC announced the assignments at a Wednesday meeting in Las Vegas.

In the main event, Kamaru Usman (15-1 MMA, 10-0 UFC) will put his welterweight title on the line against heated rival Colby Covington (15-1 MMA, 10-1 UFC). Marc Goddard will serve as the referee for the 170-pound title bout, while Derek Cleary, Sal D’Amato and Eric Colon serve as judges.

The co-headliner, which sees Max Holloway (21-4 MMA, 17-4 UFC) put his featherweight belt up for grabs against Alexander Volkanovski (20-1 MMA, 7-0 UFC), will see Jason Herzog get his first UFC title fight referee assignment, with Mike Bell, Junichiro Kamijo and Chris Lee slated as judges.

Finally, the women’s bantamweight title rematch between dual-champ Amanda Nunes (18-4 MMA, 11-1 UFC) and Germaine de Randamie (9-3 MMA, 6-1 UFC) will mark the sixth UFC title fight for referee Keith Peterson. The judges will be Dave Hagen, Ron McCarthy and D’Amato.
