A few days ago, Floyd Mayweather Jr. (49-0, 26KOs) threw down a challenge to Gennady 'GGG' Golovkin. He dared the IBO/WBA/IBF middleweight champion to move up in weight, to 168-pounds, to fight Andre Ward.

Mayweather sweetened the pot by promising to come out of retirement to fight Golovkin - if he actually moves up and hands Ward his first defeat.

Last year, Ward (29-0, 15KOs) tried to secure a fight with Golovkin (34-0, 31KOs). The fight never happened after both sides were unable to agree on the contracted weight.

While Golovkin is willing to face Carl Froch, Julio Cesar Chavez Jr., James DeGale and Bernard Hopkins at 168-pounds, his team demanded a catch-weight of 164 for Ward - who rejected anything less than the super middleweight limit.

 Golovkin has often called Mayweather his 'dream fight' and is willing to drop down to the junior middleweight limit of 154-pounds to do that fight.

"When you hear stuff about Triple G, like I said before, I told Triple G what he had to do if he wants a fight with me. He's gotta call out Andre Ward, beat Andre Ward, and then I'll fight him. I haven't seen him call out Andre Ward yet," Mayweather told Fighthype.com.

Abel Sanchez, who trains Golovkin, called Mayweather'ss idea "stupid."

The veteran trainer believes Mayweather is attempting to make Golovkin go up in order to gain a big advantage in a potential fight - because then Golovkin will "kill himself" to drop down by two divisions to 154-pounds. 

"That's how ridiculous that is. He's going to move up to move down. That's stupid, c'mon. Why would he come up to 168 and then come down to 154. Do you see what he weighed the other day....at 164 [for the WBC's 30-day weighin]. I put him on the scale at the doctor's office. He's not a guy who's a super middleweight. When he captures all of the middleweight titles, then we can talk about moving up to 168," Sanchez said.
