With five weeks to go until ONE Championship's first venture into the United States, the organization has already sold out its historic event that will be headlined by a trilogy title rematch.
The Home of Martial Arts announced that ONE Fight Night 10: Johnson vs. Moraes III, which is set to take place on Saturday, May 5, at Denver, Colorado's 1stBank Center has officially reached maximum capacity.

The momentous event showcases the biggest fight in the promotion's history when ONE Flyweight World Champion Demetrious "Mighty Mouse" Johnson defends his throne against former king Adriano "Mikinho" Moraes to complete their epic trilogy.
The card also spotlights the return of California's "Super" Sage Northcutt, who returns to competition following a four-year absence when he meets rising star Ahmed Mujtaba in lightweight action.
Also, the event features the inaugural US appearance of ONE Flyweight Muay Thai World Champion Rodtang Jitmuangnon, who faces Edgar Tabares in the evening's co-main event.
Elsewhere on the card, welterweight warriors Roberto Soldic and Zebaztian Kadestam meet in what is expected to be a firefight between two of the heaviest hitters in the division, and surely world title ramifications are on the line.
Stamp Fairtex also competes in atomweight mixed martial arts, as her journey toward gold sees her collide with American Alyse Anderson on the main card.
