Revenge will be the name of the game when Reinier de Ridder’s rematch against Anatoliy Malykhin headlines ONE 166 on Friday at the Lusail Sports Arena in Lusail, Qatar. The former two-division ONE Championship titleholder dropped the light heavyweight strap and his unblemished record to Malykhin in their previous encounter at ONE on Prime Video 5 in December 2022. He lost the fight via technical knockout in the first round.

Since that bout, Malykhin went on to win the heavyweight championship with a third-round stoppage of Arjan Singh Bhullar at ONE Friday Fights 52. With the roles reversed and “Sladkiy” sitting atop two thrones, the rematch makes for a fascinating encounter. To add to the distinction of the event, the Russian superstar will move down a weight class—to the middleweight division—in an attempt to become the first three-division mixed martial arts world champion.
