Floyd Mayweather Jr. has become a prime target of mixed martial arts fighters, the latest of which is Demetrious Johnson. Seeing as how the undefeated American boxer wants to take on inexperienced pugs, a GOAT in the MMA scene, Johnson, says he is ready to go three rounds.

According to a report from TMZ Sports, the MMA legend is down for a three-round boxing match with Mayweather. Aware of the edge that the future Hall of Famer carries, Johnson is aware that he will be at a disadvantage in a boxing ring. And should it materialize, Johnson says that is just out there to try out his boxing skills and have some fun.

"Three rounds? Just boxing? I'll do that. It'll be fun! I feel like I'll do fine," he said.

On the financial side, Johnson is aware that a fantasy fight with Mayweather can only take place if there is big money on the table. Considering it would be a GOAT (boxing) vs. GOAT (MMA) scenario, it could be something worth watching. The only question that remains is: will it sell?

Prior to that lopsided exhibition fight against Japanese kickboxer Tenshin Nasukawa, it was Conor McGregor who took on Mayweather in the boxing ring. The American boxer did win that one, although the Irishman put up a pretty good fight. Fatigue eventually caught up with The Notorious since it was scheduled for 12 rounds.

The scenario could be different if it is a three-round affair. Nasukawa failed to make it past the first round, a glimpse of things to come for Johnson if Floyd Jr. bites.

For now, all this is nothing but hearsay. Mayweather may not be paying attention until the money it can possibly raise comes out.

For Johnson, he is scheduled to make his ONE Championship debut in Japan later this month. He will take on Yuya Wakamatsu at ONE Championship: A New Era, a historic event since it will be the first time that the event will be held in Japan.

Johnson will have to settle business first before looking beyond the cage. Wakamatsu will try to give him a good fight although the 12-time flyweight world champ is ready for anything that the Japanese mixed martial artist has up his sleeve, Manila Bulletin Sports reported.

"There’s no surprise that he (Yuya Wakamatsu) is going to look through my fights and look through my wins and losses, efficiencies and deficiencies. That’s what athletes do. But a fight is a fight. A lot of people, when I get into the ring or cage with them, the first thing they notice is my speed. I’m going to go out there, fight my butt off, use my heart, my technique, and my skill set, and go out there and take it to him,” Johnson said.
