WBO featherweight champion Oscar Valdez continued his unbeaten run after overcoming English opponent Scott Quigg by unanimous decision.
Quigg was unable to fight for the belt Saturday after failing to make weight for the bout at Stubhub Center in Carson, Calif.
The 29-year-old – a former junior featherweight world titleholder – was also fined 20 percent of his official pursue.
But Quigg still put up a fight, proving to be Valdez's toughest opponent to date in his fourth title defense.
Mexican star Valdez, 27, improved his flawless record to 24-0 after the judges scored the grueling 12-round fight 117-111, 117-111 and 118-110.
"I'm gutted," Quigg said after losing for just the second time in his professional career. "There are no excuses. It was a great fight and I was in the fight all the way along.
"Early on we were trading, then we started to box, then we were trading again."
The two-time Mexican Olympian got a punishing test from Quigg (34-2-2), who appeared to benefit from that extra strength. Promoter Eddie Hearn revealed that Quigg had a right foot injury during his training camp, likely affecting his ability to make the 126-pound limit.
“Both guys showed unbelievable heart,” Hearn said. “It was a brilliant fight. Both guys aren’t human.”
Valdez landed 237 punches to Quigg’s 143. Valdez also led in power shots, 175-129.
Valdez was taken to a hospital in nearby Torrance afterward. Quigg displayed heavy damage around his eyes in addition to his broken nose.
But “Oscar was laughing” on the way to the ambulance, Robles said. “He’s a Mexican warrior. He’s the epitome of an Aztec warrior.”
Rain fell throughout the night across the Los Angeles area, but several hundred hearty fans stuck it out with help from cheap rain gear and beer. They were treated to another night of memorable fights at the outdoor ring that has hosted countless landmark bouts, albeit in California’s usually pleasant evening weather.
