All Systems Go in Las Vegas: Lightweight Doubleheader Official After Weigh-Ins

A championship doubleheader takes center stage at Virgin Hotels Las Vegas in Las Vegas on Saturday night (Sunday morning in Manila), headlined by two title clashes at the top of the lightweight division. All four title competitors made weight on Friday to make their respective world championship bouts official.

Main Event: WBC World Lightweight Title (12 Rounds)

In the evening's main event, former junior-lightweight titleholder Lamont Roach Jr. and Mexican contender William Zepeda both hit the scale at identical 134.6 pounds, comfortably beneath the 135-pound lightweight limit.

Roach, entering off highly competitive draws against Gervonta "Tank" Davis and Isaac "Pitbull" Cruz, brings his sharp technical skills into a high-octane clash against Zepeda's legendary punch volume. With both fighters stepping onto the scale focused and inside the limit, their 50-50 battle promises fireworks.

Co-Main Event: IBF World Lightweight Title (12 Rounds)

Robson Conceição (Salvador, BRA | 21-3-1, 10 KOs) — 135.0 lbs

Undefeated IBF Lightweight Champion Raymond Muratalla tipped the scales at 134.6 pounds for his world title defense. Challenger and 2016 Olympic gold medalist Robson Conceição came in right at the 135-pound division cap after shedding his underwear on the scale.

Muratalla looks to maintain his unbeaten record against the crafty Brazilian veteran in what serves as a massive co-feature bout.
