On Saturday, Aug. 26 from T-Mobile Arena in Las Vegas, undefeated rising star Gervonta "Tank" Davis will make the second defense of his IBF Junior Lightweight World Championship against undefeated challenger Francisco Fonseca (19-0-1, 13 KOs) as the 22-year-old looks to continue his reign as the youngest current champion from the U.S.

The fight will be part of the Showtime Pay-Per-View undercard to Floyd Mayweather vs. Conor McGregor.

One of the fastest-rising young stars in the sport, Davis (18-0, 17 KOs) became the youngest reigning champion from the U.S. when he knocked out Jose Pedraza in January to capture the IBF 130-pound crown.

The 22-year-old made his first title defense in style when he went to London and stopped Liam Walsh in May. Both bouts aired live on SHOWTIME.  Representing Baltimore, Davis won the 2012 National Golden Gloves championship and scored knockouts in his first eight fights after turning pro in 2013. He enters this matchup on a streak of nine-straight fights that have ended with a knockout victory.

 "I'm feeling great. Being in the same ring and on the undercard of Floyd's fight is amazing. I've worked hard to get to this point and I'm ready to put on a great show on August 26. Training has been sharp. I've been stopping a lot of guys in training. I can't wait to get in the ring and give the fans a big knockout," Davis said.

"Being on this card has been a big motivation in training. It feels great and I'm truly blessed to be in this position. I think the excitement that this card brings will be great for the sport of boxing. I'm ready to shine.

"I know I have a tough undefeated opponent who's going to come in and try to take my belt and I have to take care of business. He has some decent power so I think it's going to be an exciting fight. I've accomplished a lot at a young age. It's all because of the hard work that I've put in for my entire life. I don't complain, I just keep working every day. I'm ready to take full advantage of this chance I have. It's just one step on a long road I see to the top of this sport."
