Some boxing fans are clamoring for a Floyd Mayweather Jr. v. Gennady Golovkin bout, but Floyd’s uncle, Jeff Mayweather, does not want the matchup to happen unless Golovkin goes down from the weight class he is fighting in.

“Floyd has no business fighting a guy like Golovkin. Not so much because he’s great, but if he wants to fight Floyd, why doesn’t he come down to 147 pounds? Not 154 pounds, come down to 147 pounds just like what Floyd actually fights at,” the elder Mayweather said in an interview with Jenna J of ontheropesboxing.com.

“Floyd fought at 154 pounds just because he had the talent to go up and beat those guys. Floyd has never fought above 149 pounds, so why would he fight a guy that’s 160 pounds?”

Mayweather is the top-rated fighter in the welterweight division or the 147-pound limit and is the No. 1 pound-for-pound boxer while Golovkin is rated the best in the middleweight division or the 160-pound category. A catchweight fight — to around 154 pounds — is possible for a Mayweather-Golovkin match but it appears the American’s camp is not willing to climb the scales against the Kazakh, who is known for his knockout prowess.

Mayweather has only fought twice above 149 pounds in his career, at the 154-pound limit against Miguel Cotto in 2012, when the American won against Cotto via a 12-round unanimous decision. Mayweather also beat Oscar De La Hoya in 2007 in a 12-round split decision.

Mayweather (48-0-0, 26 knockouts) is coming off a victory over Manny Pacquiao via a 12-round unanimous decision last May 2 while Golovkin (33-0-0, 30 knockouts) beat Willie Monroe Jr. on May 16 earlier this year.
