All 18 boxers who fought on Sept. 12 at the MGM Grand in Las Vegas came up negative for the banned substances tested for in Nevada’s drug-screening panel, according to an email from state athletic commission Executive Director Keith Kizer.

That bout was broadcast on Fox Sports 2 and Fox Deportes, as was the co-feature pitting 168-pound prospect Badou Jack against Marco Antonio Periban, which ended as a draw.

The card also featured prospects Dominick Breazale, Jermall Charlo, Diego De La Hoya, Robert Easter, Terrell Gausha and Errol Spence, all of whom scored stoppage victories. A bout between unbeaten fighters Hugo Centeno Jr. and Julian Williams ended as a no contest.
