Pacquiao (59-7-2, 38 KOs), who turns 40 in December, takes his traveling road show to Kuala Lumpur, Malaysia, in a fight that should produce fireworks considering the power punching and brawling style of the 35-year-old Matthysse (39-4, 36 KOs).
When a right-left combination thudded home to send Matthysse crashing down for a third time in the seventh round referee Kenny Bayless stepped in to save him from further punishment.
Since losing his WBO welterweight belt to Australian underdog Jeff Horn, Pacquiao decided to make some changes to his team by leaving long time trainer Freddie Roach in favor of his best friend Buboy Fernandez, and leaving promoter Bob Arum to promote the Matthysse fight himself.
He was floored again in the fifth round after a flurry of punches from Pacquiao.

"I'm surprised I knocked him down so early", said Pacquiao. If he is able to defeat Matthysse comfortably and win another world title he might continue, if he loses either by knockout or lopsided hard fought decision he may decide to hang them up for good and focus on his political career in the Philippines.
"We dictated the pace".
Duterte added that he will take inspiration from Pacquiao's triumph when he holds a dialogue with Malaysian Prime Minister Mahathir Mohamad.
"I'm no longer young, so thanks to my trainer and all my team members".
