The evenly matched showdown between unbeaten rising contenders will serve as a preliminary bout to the Sept. 28 welterweight title unification bout between Errol Spence and Shawn Porter, which takes place at Staples Center in Los Angeles, Calif.
The event will air live on Fox Sports Pay-Per-View, with all participants due to meet the press for a late morning session Tuesday in Los Angeles. Also on hand will be Josesito Lopez and John Molina Jr., both of whom collide in what figures to be a wild battle of California-based welterweight gatekeepers.

Barrios (24-0, 16KOs) and Akhemedov (7-0, 6KOs) began negotiations in early July for the ordered super lightweight title fight, both carrying lengthy knockout streaks heading into what is the biggest fight for each to date.
San Antonio’s Barrios racked up his eighth consecutive stoppage with a two-round dismantling of Juan Jose Velasco this past May in Fairfax, Va. The win came two weeks prior to the most recent victory for Akhmedov, a 24-year old southpaw from Russia by way of Kazakhstan who earned a 5th round stoppage of Francisco Piña this past May in Mexico.
The bout will mark just the third stateside appearance for Akhmedov, who is managed by Vadim Kornilov. His most recent fight in the U.S. also doubles as his most notable win to date, scoring a 9th round knockout of former lightweight titlist Ismael Barroso last August.
The winner will claim the WBA “Regular” super lightweight title.
