It’s become a regular occurrence for fighters to be pulled from UFC events, with bouts often being canceled because of injuries or failed drug tests. But one of the fights originally scheduled for UFC 210 Saturday night in Buffalo won’t happen because of a different reason entirely.

Pearl Gonzalez was taken off the card Friday morning because the New York State Athletic Commission doesn’t allow female fighters that have breast implants to compete. Gonzalez was supposed to have a strawweight bout against Cynthia Calvillo, and it was the only women’s fight on the PPV.

According to the NYSAC rules, fighters who have breast implants can’t compete “due to concerns over rupture.” Calvillo told MMA Fighting’s Ariel Helwani that she was hopeful the decision would be overturned, though there’s been no indication that fight will be back on or that she will have a new opponent.

Gonzalez is 6-1 in her professional MMA career, and Saturday was set to be her first fight in the UFC.

Calvillo was set to fight on back-to-back PPVs, and she would've been the first fighter to do so since Tito Ortiz did it in 2011. Calvillo submitted Amanda Cooper at UFC 209 in three minutes and 19 seconds, picking up a win in her UFC debut and improving her overall professional MMA record to 4-0.

It was an interesting morning at the UFC 210 weigh-ins, to say the least. It appeared that UFC light heavyweight champion Daniel Cormier might not be able to defend his belt against Anthony “Rumble” Johnson in the PPV’s main event when he weighed in at 1.2 pounds over the 205-pound weight limit. However, the champ stepped on the scale for a second time just moments later, and he weighed in at exactly 205 pounds to keep the belt on the line.
