The countdown begins for an epic conclusion to 2021 at ONE: Winter Warriors! In the main event, ONE Lightweight Kickboxing World Champion Regian Eersel defends the belt against Russian sensation Islam Murtazaev. Both men are well-known for flashy moves and spectacular knockouts, so this is going to be a fight not to be missed.

The biggest tournament in women’s MMA also comes to a thrilling close, with the winner earning the right to challenge for Angela Lee’s World Title. Will former 2-sport ONE World Champion Stamp’s thunderous striking or Indian superstar Ritu Phogat’s smothering wrestling clinch the coveted ONE Atomweight World Grand Prix Championship?

The rest of the card is just as stacked, with Chinese superstar Qiu Jianliang making his ONE debut, explosive lightweight contenders Timofey Nastyukhin and Saygid Guseyn Arslanaliev squaring off, and BJJ legend Buchecha taking on hard-hitting heavyweight Kang Ji Won.
