Floyd Mayweather Jr may have an unbeaten boxing record and could retire in 2015 from professional boxing matching the 49-0 record of Rocky Marciano if he beats his last two ring opponents in May and September next year.

While he could lay claim to the unofficial title of pound-for-pound king if the dream match takes place in September if he beats Filipino champ Manny Pacquiao, it seems this early he has lost the pay-per-view (PPV) buys title.

According to the boxing Web site Boxingnews.com, the PPV king title which he got when his boxing match versus Canelo Alvarez in 2013 broke records with more than 2 million PPV purchases, is under threat. The threat comes from a bout between Saul Canelo and Miguel Cotto or between Canelo and Julio Cesar Chavez Jr which would surely outsell any PPV buys of a Mayweather versus Amir Khan bout if the two matches are held on the Cinco de Mayo weekend.

Top Rank Promotions boss Bob Arum agreed, noting that Mayweather's PPV buys in the rematch are lower than the first fight and less than Manny Pacquiao's PPV buys for his rematch with Timothy Bradley in April. The latter bout got between 750,000 and 800,000 PPV buys, which means based on Arum's estimate, the Saturday Mayweather-Maidana 2 got around 700,000, although no official data have been released yet by Showtime.

He said it is an indicator that boxing fans "are getting disgusted with Mayweather and his base is eroding."

The Web site explained that Mexican and Latin American boxing fans would not be interested in watching a Mayweather-Khan bout when pitted against a Cotto or Chavez fight on the same weekend.

As it is, the first match of Mayweather against Argentinean boxer Marcos Maidana in May is estimated to have sold only between 850,000 and 900,000 bouts, while their Saturday rematch is believed to have drawn a smaller 850,000 PPV buys.

However, it would be altogether different if the $270-million dream match finally happens. Boxing observers believe the speculated Mayweather-Pacquiao pre-retirement match would revive the declining interest in the sport as reflected in dwindling PPV numbers.
