Former four division world champion Adrien Broner has a major fight on the horizon, but he's already looking for his next opponent - and he wants that opponent to be UFC veteran Nate Diaz. 

Broner would like that fight to take place on the Showtime Pay-Per-View undercard to the crossover boxing match between Floyd Mayweather Jr. and UFC superstar Conor McGregor.

Mayweather-McGregor, booked for twelve rounds at the junior middleweight limit of 154, takes place on August 26th at the T-Mobile Arena in Las Vegas.

McGregor was submitted by Diaz in early 2016, but came back to get revenge with hard fought decision in their August rematch.

Broner would first have to overcome his next assignment, a showdown with Mikey Garcia on July 29th from the Barclays Center in Brooklyn, New York.

Although Garcia is moving up in weight, Broner is a big underdog in the fight, but believes he has more than enough to win.

"Y'all sit up and say McGregor's going to beat Floyd. This boxing game's crazy!" Broner said. "So after this fight, I just feel like, if I come out untouched, I feel like I'm going to be victorious... I feel like I should come back and fight on Floyd's undercard against Nate Diaz."

Diaz is actually one of the few UFC fighters who some boxers believe has the ability to cross over to a boxing ring.

He's often sparred with IBF, WBA, WBO light heavyweight champion Andre Ward, who often praised Diaz's boxing ability.

Diaz, like McGregor, went out last year and applied for a boxing license, but it's not entirely clear if he would even be interested.

Leonard Ellerbe, CEO of Mayweather Promotions, has made it clear in several interviews that he's not interested in any other MMA fighters appearing on the undercard and they plan to put together a full boxing undercard for Mayweather-McGregor.
