Gervonta “Tank” Davis is expecting the toughest fight of his career when he moves up by two weight divisions to face undefeated WBA "regular" super lightweight champion Mario “El Azteca” Barrios.

The fight will headline a Showtime pay-per-view card on Saturday, June 26, at the State Farm Arena in Atlanta, Georgia.

Davis has captured belts at super featherweight and lightweight, but he's never been in the ring with a legitimate 135-pounder and now he's face a big junior welterweight with punching ability.

The 25-year-old Barrios (26-0, 17 KOs) holds a six-inch height advantage over Davis.

“Gervonta Davis is looking to become a three-division world champion, and has a big undertaking in front of him in challenging Barrios for his WBA title at 140-pounds,” said Leonard Ellerbe, CEO of Mayweather Promotions. “Barrios is a warrior, and this is going to be Davis’ toughest fight to date. Atlanta, be ready for a show on June 26!”

In his last fight back in October, Davis (24-0, 23 KOs) brutally knocked out Leo Santa Cruz.

He now wants to make a similar statement against Barrios.

“I’m excited to make history on June 26 in Atlanta and become a three-division world champion,” said Davis.

“Atlanta welcomed me with open arms for my fight against Gamboa and I couldn’t wait to come back and headline a spectacular Showtime PPV card. Mario Barrios is an undefeated champion, but he hasn’t ever faced anyone like me before.

"Moving up to 140-pounds is a big challenge but I’ve been working hard in camp and I’ll be ready. Thank you to my whole team for making this historic boxing event possible. Make sure you get your tickets early because this fight is definitely selling out! Keep supporting me and I’ll fight for you!”
