Five-weight world champion Floyd Mayweather has been stripped of the WBO welterweight belt won from Manny Pacquiao in May.

Floyd Mayweather Jr cemented his place among the pantheon of boxing greats by improving to 48-0 with a unanimous decision over Manny Pacquiao on Saturday in a fight that lived up to its immense hype and price tag.

When Floyd Mayweather Jr. and Manny Pacquiao enter the ring on Saturday the stakes could not be higher, even for a bout already labeled the "Fight of the Century."

Floyd Mayweather Jr.'s dominating win over Canelo Alvarez was the richest fight ever, a box-office smash at the arena and on television.

Mike Tyson was the closing act, which seemed appropriate since he knows a thing or two about headlining shows on the Vegas Strip.

The former world heavyweight boxing champion had hoped to prove his critics wrong and show that he could comeback from retirement into an entirely new sport and revive some of his past glory.

Manny Pacquiao will return to the ring Nov. 24 to meet Brandon Rios in a welterweight bout in Macau, the eight-division world champion's promoter said Monday.

The two meet in a scheduled 12-round welterweight title match at the MGM Grand hotel in what will be Mayweather's first fight in a year.

Fighters will compete for sponsored teams, box without protective headgear and earn $1,000 to $3,000 a month.

For all the things President Obama says he can't do because of the political gridlock in Washington, he can right a century-old wrong simply by picking up a pen.
