ONE Championship (ONE), the world’s largest martial arts organization, today announced the first two matchups for ONE 173, the promotion's blockbuster return to the Ariake Arena in Tokyo, Japan, on Sunday, November 16.

The announcements were made during a press conference at Spiral Hall in Tokyo earlier this afternoon.

In the main event, an undisputed ONE Featherweight Kickboxing World Champion will be crowned when reigning king Superbon squares off against interim titleholder Masaaki Noiri in a highly anticipated World Title unification bout.

Noiri captured the ONE Interim Featherweight Kickboxing World Title with a stunning knockout victory over Tawanchai PK Saenchai at ONE 172 this past March, setting the stage for this showdown with Superbon.

In the co-main event, undisputed ONE Heavyweight MMA World Champion “Reug Reug” Oumar Kane will defend his gold against former titleholder Anatoly Malykhin in a highly anticipated rematch.

“Reug Reug” scored a historic upset in their November 2024 meeting at ONE 169, becoming the first-ever MMA World Champion from Senegal and handing Malykhin the only defeat of his professional career.

Still ONE Middleweight and Light Heavyweight MMA World Champion, the Russian is now seeking redemption, while Kane is eager to cement his legacy and close the door on this heavyweight rivalry. 

ONE 173 will emanate live from the Ariake Arena on November 16, with global broadcast details being announced at a later date. Pre-sale tickets will be available tonight beginning at 7 p.m. JST via ePlus.

Tickets will go on sale to the general public at 10 a.m. JST on Saturday, July 5.

Additional marquee bouts for ONE 173 will be announced in the near future.
