ONE Championship's upcoming return to the United States has taken a major hit.
After fortifying its status among combat promotions in Asia, ONE began its pursuit of further prominence on US soil by debuting in the region last year. The successful ONE Fight Night 10 card took place at the 1stBankCenter in Broomfield, where Demetrious Johnson, Rodtang Jitmuangnon, and Stamp Fairtex were among the major winners.
The organization is back in Colorado almost 16 months later, with Denver's Ball Arena playing host to ONE's sophomore US event. But when it comes to putting on a stacked lineup for the American audience, not everything has gone to plan this time around.
ONE 168, set for this Friday, September 6, first lost its strawweight MMA title headliner between champion Xiong Jing Nan and atomweight queen Stamp after the latter tore her meniscus in May.
And just as fight week gets underway, the upcoming card has taken another huge blow...
Ruotolo Out Of Musumeci Super Fight, 'Dealing With Injuries' After CJI Triumph
In the absence of Xiong vs. Stamp, another champ vs. champ showdown was cemented as the main event in Jonathan Haggerty vs. Superlek Kiatmoo9. Co-headlining, meanwhile, was slated to be a submission grappling title fight.
Among those raising the prominence of submission grappling in ONE are Kade Ruotolo and Mikey Musumeci. The pair were scheduled to do battle for the former's lightweight title at ONE 168, with "Darth Rigatoni" moving up three weight classes to take on the challenge.
But after emerging $1 million richer from the inaugural Craig Jones Invitational last month, Ruotolo is carrying injuries and has been left unable to share the Circle with Musumeci in Denver.
"Just going to start by saying this year has been a hectic one," Ruotolo wrote on Facebook. "I am proud for accomplishing my goals this year of competing in gi, nogi and mma. I’m unfortunately dealing with injuries. I know a lot of people, including myself and Mikey were looking forward to the One match in Denver but unfortunately it’s off.
"Im going to be recovering alongside my brother and hope to get back to the mats asap. Massive thank you to @onechampionships for being the best martial arts platform @yodchatri," he concluded.
It's unclear whether Musumeci will remain on the lineup and receive a replacement opponent. But should he and Ruotolo be off the card, ONE 168 will have lost one of its biggest matchups and both of its big-name US athletes.
