Grappling champion Kade Ruotolo will face his biggest MMA test to date on Dec. 18, when he returns to the ONE Championship ring in Bangkok, Thailand, to face former titleholder Ok Rae Yoon, MMA Fighting has learned.
According to the promotion, ONE Fight Night 50 will air in U.S. primetime.
Ruotolo holds the ONE submission grappling belt, but has been more focused on his MMA endeavor as of late, winning his four fights in Asia with a 100 percent finishing rate.
The 23-year-old stopped Hiroyuki Tetsuka with a second-round knockout in his most recent bout, improving his record after three tapouts in his first MMA appearances.
Yoon, a veteran of 17 wins in 24 professional MMA bouts, holds victories over stars like Eddie Alvarez and Christian Lee in 2021, capturing the ONE title that year.
The South Korean veteran enters the ring looking for redemption, however, after dropping decisions in his most recent MMA bouts versus Alibeg Rasulov and Lucas Gabriel.
