MEXICO CITY – Daniel Zellhuber showed out for 15 minutes at UFC Fight Night 237 , something he didn’t expect to happen. The UFC lightweight prospect thought either the referee, doctor or corner of opponent Francisco Prado was going to interfere at some point in their main card bout given the amount of damage he was dishing out. Zellhuber (15-1 MMA, 3-1 UFC), who defeated Prado (12-2 MMA, 1-2 UFC) in a unanimous decision, was surprised that the fight wasn’t stopped.
