The CEO of ONE Championship Victor Cui has told Fox Sports that all current world champions on the ONE roster will retain their belts under its new weigh-in system.

Cui told Fox Sports presenter Steve Dawson that all current champions will move up a weight class under the sweeping new changes introduced earlier this month. For example current bantamweight champion Bibiano Fernandes will move up into the featherweight division.

It is unknown if high-profile champions like welterweight champ Ben Askren or lightweight champ Shinya Aoki will move up and Cui admitted there would be some case-by-case exceptions.

“Of course there might be some athletes that will stay in their existing weight class because they have their diet or weight training in a different program and we will consider that. But in theory it’s quite simple, everybody moves up a weight class together and in unison.”

On the 24 December ONE announced that it would ban weigh-cutting by dehydration and institute a new set of regulations and policies governing the weigh-in procedures and contracted weight limits.

Athletes will now compete at their “walking-weight”, which will be determined by a system to track a fighters weight on a regular basis, including random weight checks.

“I think we are on the right track for growing the sport and the key is, in everything we do, to continually strive and improve and put the the health and safety of the athletes front and centra as it should be.”
