Floyd Mayweather Sr believes his son will continue boxing beyond his fight with Andre Berto on September 12.
The unbeaten Mayweather can match Rocky Marciano's legendary 49-0 record with victory over Berto, and despite insisting the bout is his last as a professional, Floyd Sr believes the chance to surpass that record could prove too tempting.
After out-classing pound-for-pound rival Manny Pacquiao in the richest fight in history in May, Mayweather Jr, 38, has decided to call time on his glittering career following his clash with Berto and the end of his contract with Showtime.

Floyd Sr said: "Myself, I can't say that Floyd is going to fight any more but I think he might fight again. If things are going right for him and people are doing what they're supposed to do, it's more than likely he's going to fight. That's my belief.
"I definitely think it's a record that needs to be broken. I think Floyd can break it but I want to make sure he's ready. When I say ready, I mean he feels good and is ready to go. You can' be ready when you don't feel good.
"I love everything my son has done in boxing. He controlled boxing. Boxing today is all about Floyd. He controls it right now today. Nobody else. Floyd control's boxing."
Mayweather Jr received wide spread criticism on the announcement of his fight with Berto, the American being see as an easy option following three defeats in his previous six bouts, with bookmakers making Mayweather as short as 1-100 to emerge victorious.
Should Mayweather decide to continue, British rivals Amir Khan and IBF champion Kell Brook could be potential opponents for the pound-for-pound king, with fellow American and WBA champion Keith Thurman another potential candidate.
