ONE Championship returns to the U.S. this weekend for its biggest event in recent history, back where it all began for MMA inside Denver, Colorado - and the promotion brings with it a card stacked from top to bottom.
ONE 168: Denver goes down inside Ball Arena this Saturday, 7 September, with a star-studded event and a monumental headliner. There, two-sport ONE Bantamweight World Champion Jonathan Haggerty defends his Muay Thai crown against ONE flyweight kickboxing king Superlek Kiatmoo9.

Ever since arriving in ONE in 2019, Haggerty has always stood out from the bunch. "The General" captured the ONE Flyweight Muay Thai World Title in his second promotional bout after dispatching the legendary Sam-A Gaiyanghadao across five rounds.
But after losing his belt to Rodtang Jitmuangnon and failing to win it back in a rematch, plus multiple issues making weight, the Brit moved up to bantamweight and never looked back.
He immediately shook up the division after defeating former king Nong-O Hama at ONE Fight Night 9 in April 2023, knocking out the legend in the first-round to claim the belt.
Haggerty then entered rarified air by knocking out ONE Bantamweight MMA World Champion Fabricio Andrade for the weight bracket's vacant kickboxing belt back in November at ONE Fight Night 16.
Sitting proudly as a two-sport king, nobody has been able to touch the new and improved version of "The General." But that's what striking great Superlek looks to do this weekend.
Much like his English foe, "The Kicking Machine" is on a 10-fight winning streak dating back to 2022. Many names have fallen to him during this time, including Nabil Anane, Takeru Segawa, and Rodtang himself.
Superlek claimed the ONE Flyweight Kickboxing World Title back at ONE Fight Night 6 in January 2023. And he's continued to go from strength to strength ever since, taking on all comers.
The Thai stomper has already solidified himself as a great in the all-striking realms. But what would secure his legacy forever is dethroning Haggerty and capturing the bantamweight this weekend at ONE 168: Denver. Here is a look at the telecast, live streaming and fight card details:
