That event was overseen by the California State Athletic Commission (CSAC), which has advised those six fighters to move up a weight class after each of them came in 15% or more over their weigh-in weights on fight day.
Bermudez had to have his bout at catchweight, because he was unable to make the bantamweight weight limit at UFC 241.
CSAC Representative Patricia Blackstock, in an email to MMA Junkie, would state that all six fighters can stay at their current weight classes if they all can prove that they can make weight and fight safely.
“If those fighters wish to fight below the weight class that CSAC moved them to, then they will have to enroll in a nutrition program and work with the (UFC Performance Institute or a similar place) to address their weight/weight gain,” Blackstock wrote. “Their nutrition program and findings from the PI will have to be sent to CSAC for review and approval before the fighters are moved down in weight class.”
There has been no comment yet from any of the six fighters as to whether or not they plan on changing weight classes in the future.
