Ronda Rousey vs Floyd Mayweather Jr. 'in rule-less fight': I will win, says UFC champ

Ronda Rousey has thrown down the challenge and not since the possibility of Serena Williams taking on a Top 20 male tennis player has been bandied about has the battle of the sexes been played up so much.

In her Reddit AMA on Monday night, the UFC women's bantamweight champion was asked if she could beat Floyd Mayweather Junior "in a ruleless fight”.

Huffpo quotes her as saying: “Floyd is one of the best boxers of all time. He would definitely beat me in a boxing match.

“I unfortunately don't get into ‘matches’.

“I fight for a living. In a no rules fight, I believe I can beat anyone on this planet.

“Boxing is a sweet science with strict rules that I respect very much and aspire every day to improve at. But you said rule-less fight, and that's my honest answer.”

Mayweather on ESPN's ‘SportsCenter’ last week was quoted as saying: "I've yet to see any MMA fighter, or other boxer, make over $300 million in 36 minutes," "When she can do that, then call me."

Rousey beat Mayweather for ‘Best Fighter’ award at the recent ESPYs.

“I wonder how Floyd feels being beat by a woman for once,” she said after the win.
