Former lightweight king Teofimo Lopez hopes to conquer a second weight class. That journey begins Saturday against Pedro Campa in the 10-round junior welterweight main event at the Resorts World Event Center at Resorts World Las Vegas.



In the eight-round co-feature, unbeaten Puerto Rican junior middleweight standout Xander Zayas takes on Elias Espadas. Lopez-Campa and Zayas-Espadas will be broadcast live on ESPN, ESPN Deportes and ESPN+ at 10 p.m. ET/7 p.m. PT.

The undercard — streaming live and exclusively on ESPN+ — includes the return of Las Vegas-born junior lightweight contender Andres Cortes against the bruising Abraham Montoya. Promoted by Top Rank, tickets starting at $40 are on sale now and can be purchased at Etix.com.

Lopez, Campa, Zayas, and Cortes kicked off fight week Wednesday with a media workout at the Top Rank Gym.

Lopez (16-1, 12 KOs), whose run up the lightweight ranks included a legacy-defining victory over Vasiliy Lomachenko, went through the paces for more than 30 minutes.

He hit the mitts with his father/trainer, Teofimo Lopez Sr., and even conducted an impromptu pushup session in the middle of the ring. Following last November's split decision loss to George Kambosos Jr., he sets his sights on Campa (34-1-1, 23 KOs), an accomplished veteran who is 7-0-1 since the lone defeat on his ledger.
