Room for error no longer exists for Cynthia Calvillo or Nina Nunes.
Hopefuls in the Ultimate Fighting Championship women’s flyweight division, they will toe the line against one another in the featured UFC on ESPN 39 prelim this Saturday at the UFC Apex in Las Vegas. Calvillo finds herself on a three-fight losing streak that now covers more than two years. She last appeared at UFC Fight Night 179, where she bowed to a second-round technical knockout against Andrea Lee on Nov. 13. Nunes, meanwhile, enters the cage on the heels of back-to-back losses.
