Fast-rising junior welterweight prospect Mario Barrios will fight Richard Zamora in a 10-round bout announced on Monday. It will serve as the co-feature of the "Showtime Championship Boxing" card on Feb. 9 at the Dignity Health Sports Park, formerly the StubHub Center, in Carson, California.

Showtime also announced that the tripleheader (10 p.m. ET), headlined by the previously announced fight between junior lightweight world titlist Gervonta Davis and former three-division world titleholder Abner Mares, will open with a 10-round lightweight fight between former junior lightweight titlist Javier Fortuna and Sharif Bogere.

The search had been on for an opponent for Barrios (22-0, 14 KOs), 23, of San Antonio. Zamora (19-2, 12 KOs), 25, of Mexico, got the call when his fight against Logan Yoon, which was scheduled as the co-feature on Showtime's "ShoBox: The New Generation" card on Friday night, was canceled earlier on Monday because Yoon suffered a knee injury and withdrew from the bout.

Barrios has won six fights in a row by knockout. Zamora, who will be fighting outside of Mexico for the first time, has won five fights in a row since suffering a first-round knockout loss to Antonio Moran in March 2017.

Fortuna (33-2-1, 23 KOs), 29, of the Dominican Republic, has not fought since a fourth-round no decision against Adrian Granados on Showtime in June. The fight was ruled a no decision when Fortuna was injured after he accidentally fell out of the ring.

Bogere (32-1, 20 KOs), 30, a native of Uganda fighting out of Las Vegas, is 9-0 with a no contest since losing a unanimous decision to Richar Abril in a lightweight world title bout in 2013.
