"I'm here again for another big fight. I'm so thankful to the fans for all their support," Pacquiao said at the final press conference this week.

Pacquiao, 46, fell short in his attempt when his fight with WBC champion Mario Barrios ended in a majority draw Saturday night.

He became the oldest welterweight world champion in history at the age of 40.

Pacquiao has fought 72 times compared to 32 fights for Barrios, who was not born when Pacquiao made his pro debut in 1995.

The Ukrainian dropped Dubois twice in the fifth — the second time with a lunging left cross.

"I'm sorry [Dubois], it's sport. My people wanted this win," Usyk told DAZN.
