Get ready for the biggest night of the summer, as ONE Championship returns to the iconic Lumpinee Boxing Stadium with ONE Fight Night 13: Allazov vs. Grigorian on Prime Video, which broadcasts live in U.S. primetime on Friday, August 4!

Fresh off his highlight-reel World Title victory, ONE Featherweight Kickboxing World Champion Chingiz Allazov will defend his gold for the first time and try to earn some redemption in the headline attraction. He’ll stand toe-to-toe with heated rival Marat Grigorian, who is determined to get a second victory over the divisional kingpin and win the richest prize in the sport.

In the co-main event, ONE Flyweight Submission Grappling World Champion Mikey Musumeci, who is widely considered the best pound-for-pound grappler in the sport today, will make his third World Title defense. But standing across from him will be strawweight MMA king Jarred Brooks, a bona fide wrestling standout who is moving up in weight for his crack at two-sport glory.

And in an MMA showdown that’s been two years in the making, 17-time BJJ World Champion Marcus “Buchecha” Almeida will finally collide with Senegalese Wrestling Champion “Reug Reug” Oumar Kane, and whoever emerges victorious could earn the next ONE Heavyweight World Title shot.

The card features several more of your favorite martial arts superstars, including ONE Featherweight Muay Thai World Champion Tawanchai PK Saenchai, 19-year-old Thai prodigy Anna “Supergirl” Jaroonsak, and former bantamweight MMA king John Lineker.
