Oscar De La Hoya has been making some noise about coming out of retirement as a 42-year-old. If that happens, Floyd Mayweather says he will accommodate him.

"If he wants to, we can rock and roll in September," Mayweather told reporters.

"He said he wanted a rematch," Mayweather said. "So if Oscar wants it, he can get it."

Mayweather defeated De La Hoya by split decision when they fought for the WBC super-welterweight title (154 pounds) on May 5, 2007.

A rematch never materialized. Mayweather fought Ricky Hatton in December 2007, then announced his retirement. He came back to fight Juan Manuel Marquez in September 2009 and has been active since.

De La Hoya's last bout before retiring was an eighth-round loss against Manny Pacquiao in December 2008.

Mayweather, 38, just beat Pacquiao by unanimous decision in May and earned about $275 million in the process. It will be tough to duplicate that kind of a payday, but another fight with De La Hoya should still generate significant revenue.
