Floyd Mayweather Jr. will return to the ring for the first time since boxing's richest fight ever, facing Andre Berto on Sept. 12 in what Mayweather has said will be his final fight.

The welterweight title bout doesn't figure to be nearly as lucrative as Mayweather's May 2 fight with Manny Pacquiao that earned him a reported $220 million. But it will still be sold on pay-per-view, even though Mayweather will be an overwhelming favorite to win for the 49th time in as many fights as a pro.

Berto, a 2004 Olympian, was once thought of as a rising star but has lost three of his past six fights. Two of those losses were to Robert Guerrero and Victor Ortiz, fighters that Mayweather beat easily.

"I always bring my A-game and this fight against Andre Berto is no exception," Mayweather said in announcing the bout. "He's a young, strong fighter who is hungry to take down the best."

The fight is the last in a six-bout deal Mayweather has with Showtime, and the boxer has said repeatedly he will retire when the deal is finished. The 38-year-old retired once before but came back to fight after taking a short break.

Stephen Espinoza, executive vice president and general manager for Showtime Sports, dismissed criticism that the fight looks like a mismatch, saying there were complications trying to do a deal with Amir Khan and not a big pool of other fighters to choose from.

"He's one of those fighters who never fails to entertain," Espinoza said about Berto (30-3).


Canucks' Sutter signs extension

The Vancouver Canucks signed recently acquired center Brandon Sutter to a five-year contract extension at an average annual value of $4.375 million per season.

The Canucks acquired the 6-3, 190-pound Sutter and a third-round draft pick in 2016 from the Pittsburgh Penguins last week for Nick Bonino, Adam Clendening and a 2016 second-round draft pick.

The 26-year-old Sutter, who has a cap hit of $3.3 million in 2015-16, was set to become an unrestricted free agent next summer, but the son of former NHL player and coach Brent Sutter now is under contract through 2020-21.
