Another Boxing vs. MMA showdown could be on the horizon for 2020.

According to UFC President Dana White, he's held discussions with the team behind multi-division champion and Olympic gold medal winner Claressa Shields, to crossover to MMA to have a showdown with UFC champion Amanda Nunes.

In the last few years, Nunes has blasted out a who's who of female fighters in the UFC. Shields has dominated the competition in boxing.

Shields will be ringside on Saturday night in Las Vegas, when Nunes defends her UFC bantamweight world title against Germaine de Randamie in the main event of UFC 245.

“Claressa Shields is coming. She’ll be here Saturday to watch the fight. She’s coming to watch the fight, and I will be honest with you, Claressa Shields’ people and I have talked. I don’t know, we’ll see. We’ve talked," White told BT Sport.

“I know they’re both interested in it, too. We’ll see how this whole thing plays out. We have a lot of respect for her, too, and she’s going to come to the fight and should be fun.”

Shields will fight for the vacant WBC, WBO junior middleweight titles against Ivana Habazin on January 10, televised by Showtime from Atlantic City.

Back in 2017, White came together with Showtime to stage the mega-fight between UFC superstar Conor McGregor and five division champion Floyd Mayweather. The contest became the second biggest selling pay-per-view of all time. It only ranks behind Mayweather's 2015 encounter with Manny Pacquiao.

Mayweather stopped McGregor in the tenth round of a contest that was sanctioned under traditional boxing rules.

Considering the massive amount of money that was generated from the Mayweather-McGregor showdown, countless boxers and MMA fighters are calling each other out for crossover fights.

Nunes-Shields would not come close to the success of Mayweather-McGregor, but it would create crossover interest from both sports.
