Several fighters at UFC San Diego gained more than 10 percent of their body weight between official weigh-ins and fight night, the California State Athletic Commission determined. But only one will receive a recommendation to move up.

Tyson Nam gained 16 percent of his body weight in the 24 hours before his fight, competing at 146.2 pounds, or 20.2 pounds heavier than the 126-pound park for his non-title flyweight bout against Ode Osbourne, according to fight-night weights released by the CSAC and obtained by MMA Fighting.

As a result, the commission will request Nam move up a weight class to bantamweight, CSAC Executive Director Andy Foster told MMA Fighting. But the UFC veteran can also continue to compete at flyweight if he can get a doctor to certify he can safely compete in the lower division. Nam earned a “Performance of the Night” bonus for his incredible knockout of Ode Osbourne this past Saturday’s preliminary card at Pechang Arena in San Diego.

Several other UFC San Diego fighters gained in excess of the 10 percent cutoff recommended by the CSAC as a part of a 10-point plan enacted in 2017 to prevent extreme weight-cutting in MMA. Headliners Marlon Vera (12 percent) and Dominick Cruz (14 percent) were among those who exceeded the limit. They will receive letters notifying them of the overage, but will not be ordered to move. Foster said the overall numbers reflected a large improvement from previous events.

In total 8 of 13 fights, or 61 percent, were within the weight gain limits recommended by the California commission.
