Undefeated "regular" junior welterweight world champion boxer, Mario "El Azteca" Barrios (26-0, 17 KOs) is only days away from his upcoming fight against four-time world champion Gervonta “Tank” Davis.

Barrios' fight with Davis (24-0, 23 KOs) will take place on Saturday night in Atlanta. The bout headlines a Showtime pay-per-view telecast that begins at 9 p.m. ET/6 p.m. PT.

Davis is taking a very big risk in moving up to the junior welterweight division to face a much bigger fighter, who is already established in the weight class with a string of knockout victories.

Barrios views Davis as a the perfect opportunity to catapult himself into the big time - when taking into account Davis' star status in the sport and promotional back of Mayweather Promotions.

Davis, who knocked out nearly every opponent in his path, has promised another sensational win after blasting out Leo Santa Cruz last October, with a brutal uppercut to send the Mexican star out cold in their own pay-per-view encounter.

“Right now, my dreams and aspirations are becoming reality as these special moments are happening in real time," Barrios said.

"We arrived in Atlanta last night and El Azteca is in warrior spirit, and best believe I’m coming for this man who is trying to take my belt. I want to thank all my San Antonio fans and everyone in Texas for their continued support. I want to let them know that we are going into battle together, as one. Tank has his army of fans, and I have mine. It’s going to be a great fight and may the best man win.”
