Well, this may be a first in UFC history.
Pearl Gonzalez, who was supposed to fight Cynthia Calvillo at UFC 210, has been taken off the card because she has breast implants.
I'm told the Calvillo-Gonzalez has been canceled. Per NYSAC, female fighters are not allowed to have implants, thus ruling out Gonzalez.

From MMA Mania:
According to the old boxing statutes, the concern is that repeated blows to the bosom might rupture the implant, putting the fighter’s health at risk.
The UFC has not made an official statement yet.
