A bout from UFC 210 has been reportedly cancelled at the very last minute by the New York State Athletic Commission. Strawweights Cynthia Calvillo vs. Pearl Gonzalez was supposed to happen on the pay-per-view portion of the card, but after the official weigh ins, the NYSAC scrapped Gonzalez from bout.
