Manny Pacquiao says he will prove “age is just a number” when he fights as a 40-year-old for the first time against Adrien Broner in Las Vegas on Saturday.
The Filipino will defend his WBA world welterweight title against the former four-weight world champion.
It will be his 70th professional fight, coming some 24 years after his debut.
“This is a challenge because it is my first fight as a 40-year-old,” said Pacquiao. “I have something to prove to everyone about what that means.”
He added: “Age is just a number. What matters is how you prepare and that you’re working hard.”
