Floyd Mayweather tells Ronda Rousey to shut up until she does this

Ronda Rousey has jabbed at Floyd, but Mayweather just dropped the hammer.

Floyd Mayweather is one of the most entertaining boxers in the game, recording a 48-0 record, with his next fight against Andre Berto in September from Las Vegas.

While the electric boxer was hyping his fight on ESPN Thursday, Steve Levy brought up UFC's Ronda Rousey, who hasn't been hesitant to take jabs at the boxer.

Mayweather was quick to respond to the undefeated UFC champion, noting, "I've yet to see any MMA fighter, or other boxer, make over $300 million in 36 minutes," Mayweather said, via MMAFighting.com. "When she can do that, then call me."

UFC has taken shots at Mayweather before, but it was Rousey who trolled the champ during her Entourage promotion and at the ESPYs. It seems like this "rivalry" isn't quite as one-sided as we initially thought.
