Driven: Shawn Porter

"Showtime" (27-2-1, 17 KOs) will enter the ring against former title challenger Thomas Dulome (24-2, 18 KOs) in a 10-round fight which will headline preliminary bouts before Mayweather and McGregor enter the ring.

"As always I'm just excited to get in the ring and perform," said Porter per the press release. "I think fighting on network television again will be awesome and a huge opportunity for me. And to do it before one of the most anticipated sporting events ever is even more exciting. I feel like I've earned this spot and I'm ready to give the people the appetizer they deserve! 'Showtime' Shawn Porter never disappoints and I will prove that again on August 26."

"I'm thankful for this opportunity on August 26," said Dulorme. "I have been blessed with great fans and my last fight helped me to gain a little more recognition, but I am just getting started. I had a great performance back in January with a TKO victory, and this fight I plan to bring that same mindset into the ring. I am ready to win and to fight on Floyd Mayweather's card is a blessing. I have a great team behind me and I am confident. I know my opponent is tough, but he's just the opponent I need to really show everyone that I am even tougher."

They'll be fighting on Fox and Fox Deportes beginning at 7pm EST/4pm PST.
