Earlier this week, trainer Freddie Roach said he was confident that his boxer, Manny Pacquiao, would eventually face Floyd Mayweather Jr. because both boxers are running out of opponents. Roger Mayweather, uncle and trainer of Floyd, disagrees.

Pacquiao returns next Saturday night, at the MGM Grand in Las Vegas, in a rematch with WBO welterweight champion Timothy Bradley. Mayweather comes on May 3rd, at the same venue, against Marcos Maidana in a welterweight unification.

"He ain’t gonna fight Floyd to save his mother***ing life. He ain’t gonna fight Floyd, period. I don’t give a damn if he does get past Bradley, he ain’t gonna fight Floyd anyways," Roger said to On The Ropes Boxing Radio.

Roger says Mayweather will dominate Maidana in their fight. Nobody can defeat Mayweather at 147, says Roger. But a very big boxer, with boxing ability, like an Andre Ward, probably could.

"The only guys that could actually beat my nephew is a guy that out weighs my nephew, if he out weighs my nephew and he can box, those are the only kind of guys that can beat him. But guys in his weight class, nah, guys in his weight class ain’t going to beat him," Roger said.
