Reigning and undisputed ONE lightweight Muay Thai world champion ‘The Immortal’ Regian Eersel of Suriname and the Netherlands has entertained the idea for potential cross-divisional superfights with fellow ONE World Champions.The 32-year-old multi-sport monster is open to facing other big names in ONE Championship who are willing to move up to his weight class.The Amsterdam native explained that ONE Championship’s hydration testing protocols prevent him from cutting weight by dehydration, so if his fellow titleholders want to fight, they have to move up to lightweight to face him.Speaking during the ONE Fight Night 34 post-fight interviews, Eersel shot out a challenge to his fellow ONE stars. View this post on Instagram Instagram Post‘The Immortal’ addressed the media:"If they can come up to my weight class, it will be awesome. I can't go down because of the hydration test. Without hydration tests, I can go down, but with hydration tests, I can't go down. So they have to come up to my weight class, but I would love to. If they come up, I would love to welcome them to the big boys."ONE Fight Night 34: Eersel vs. Jarvis on Prime Video was broadcast live on August 2 from the iconic Lumpinee Stadium in Bangkok, Thailand.
