Weight gains: Jorge Masvidal added nearly 30 pounds overnight before Nate Diaz boxing match

Jorge Masvidal weighed almost 15 pounds more than Nate Diaz on fight night.

In California, fighters have their weights checked on the day of their fights – not just when they have to hit their marks on the scale.

In 2017, the California State Athletic Commission put a plan in place to try to cut back on excessive weight cutting. Within those rules was a cap on how much a fighter could gain from the official weigh-ins to the fight.

If a fighter gained more than 10 percent back before the bout, the commission then could make a recommendation that he or she move to a higher weight class. If a fighter gained more than 15 percent, the commission had plans in place to potentially cancel fights.

At “Last Man Standing”, which took place Saturday at Honda Center in Anaheim, Calif., 11 of the 22 boxers on the card gained more than 10 percent of their weight back – including Masvidal, who lost to Diaz in the main event. No fighter exceeded the 15 percent threshold.
