Floyd Mayweather Sr. Cautions His Son About Returning

LAS VEGAS - Should Floyd Mayweather's boxing career now be over, as the undefeated American insisted after easily beating Andre Berto in their welterweight showdown on Saturday, his place among the sport's very best is assured.

He will certainly be remembered as one of the greatest defensive practitioners of all time because of his remarkable ability to stay away from danger in the ring, right up there with fighters such as Pernell Whitaker and Willie Pep.

As for his brash claim to be 'TBE' (The Best Ever), that will fall to historians to judge, though many pundits would be reluctant to put him on a pedestal alongside true greats like Sugar Ray Robinson, Muhammad Ali, Joe Louis and Roberto Duran.

However his trainer and father, Floyd Mayweather Sr., is less sure and has cautioned his son -- if he does return -- to do so no more than six months after Saturday's fight because of his advancing age as a boxer.

"Fighting is never easy to do," Mayweather Sr. told reporters shortly before his son's post-fight news conference. "If you don't want to fight, you better quit right then.

"When your mind is telling you, 'I don't want to do this no more,' you better not do it no more. Because if you continue to do it, you're going to get hurt."
