The main element

In a champion-versus-champion battle, welterweight titleholder Kyamryan Abbasov takes on lightweight champion Christian Lee, who is moving on to a second belt. Abbasov won the belt in 2019 against Zebastian Kadestam. He defended it almost a year later with a fourth-round TKO of James Nakashima. Earlier this year, he went on to shoot for a second belt himself, but was passed out by Rainier de Ridder. The loss snapped a five-fight winning streak.

Lee is coming off a second-round knockout of Rae Yoon Ok in August to regain the title he lost in September 2021. Lee had won seven of eight fights and Ok had a six-fight winning streak before his loss.
