Fight Mayweather or retire, Arum tells Pacquiao

Veteran boxing promoter Bob Arum believes Manny Pacquiao should retire from the sport soon unless he can land a lucrative rematch with Floyd Mayweather.

Arum, who promoted Pacquiao during the Filipino icon's golden years, told the World Boxing News website he wanted to see the 40-year-old hang up his gloves soon.

Pacquiao, who won a bruising 12-round battle with Keith Thurman to capture the WBA welterweight crown in July, has not scheduled his next fight.

But Arum said he believed Pacquiao, who turns 41 in December, would be risking lasting damage if he extends his career much further.

"Pacquiao, I promoted him for many, many years," Arum told World Boxing News.

"He's an exceptionally good human being, really a fine guy, extraordinarily charitable and a delight.

"But he's (almost) 41-years-old. And if you're 41 you can't take punishment. You can't take blows like he did in the Thurman fight.

"Sure, he won that fight - but he took a lot of punishment. That punishment is going to have a serious effect on how he lives the rest of is life."
