On Saturday, Aug. 26 from T-Mobile Arena in Las Vegas, WBA Light Heavyweight Titlist Nathan Cleverly will defend his title against former 168-pound world champion Badou Jack "The Ripper", who is stepping up in weight and into this world title tilt.

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

A two-time world champion at light heavyweight, Cleverly (30-3, 16 KOs) bounced back from a defeat to Andrzej Fonfara in a 2015 Fight of the Year contender to defeat hometown champ Juergen Braehmer last October to pick up his WBA title.

Cleverly's previous title reign saw him take down the likes of Tony Bellew, Nadjib Mohammedi, Shawn Hawk and Tommy Karpency before dropping a contest to Sergey Kovalev. The Wales resident will make his fourth start in the U.S., having won two of his first three contests stateside.

Now fighting in the 175-pound division, Jack's final fight at 168 pounds came in a title unification on SHOWTIME in January against James DeGale.  Jack (21-1-2, 12 KOs) shook off an early knockdown to floor DeGale in the final round in a close majority draw in which both fighters retained their belts.

"Everything is great in training camp. I've been in training for about seven weeks getting ready for this matchup. I'm excited and happy to be a part of such a big event. I think this weight is going to be better for me. I'm going to have more power. I'll be more athletic and style-wise I prefer to fight bigger guys. I can use my speed, but I also like to go inside and break my opponent down. It's harder if I have to chase them, but the big guys are going to be right there," Jack said.

"Cleverly has a high work rate and he's very tough. He's going to come to fight. That's what we want. It's a good first fight for me at this weight. I'm excited to work hard these next two weeks and get to fight night. He's been in some good fights but I'm different than anyone he's faced. I'll show how my skills translate to light heavyweight.

"It's really a blessing to be in this position. I'm happy because a lot of other fighters don't get to be on this stage. I'm so thankful to my whole team. I won't let the fans down and on August 26, I'm coming to steal the show. I've done everything right to get to this point. It's an honor to be in this position. I just have to take care of business."
