Floyd Mayweather is ready to fight Sergio Martinez if the match-up against Manny Pacquiao proved elusive.Promoter Lou DiBella told BoxingScene.com that he briefly spoke with the representatives of Floyd Mayweather Jr. (43-0, 26KOs), to see if there was any interest in fighting Sergio Martinez (48-2-2, 27KOs), the WBC's Diamond champion.Martinez would drop down to a reasonable catch-weight, like 154-155, to face Mayweather.DiBella has very close ties with Mayweather's business manager, Al Haymon, who also manages DiBella boxers Andre Berto and Jermain Taylor.According to DiBella, Manny Pacquiao is the top priority for Mayweather. But, if Pacquiao is 100% off the table for Mayweather's return, scheduled for May 5th at the MGM Grand in Las Vegas, Martinez would be considered."There was a very brief conversation with Mayweather's representatives where it became clear that in the eventuality that it's clear that there won't be a Pacquiao fight, and I don't think they've hit that point yet, that they would consider Sergio," DiBella told BoxingScene.com.
