WBA welterweight champion Yordenis Ugas will be looking to score a big upset on Saturday night, when he plans to retire 42-year-old Manny Pacquiao.

The two fighters will collide in the main event of a Fox Sports pay-per-view from the T-Mobile Arena in Las Vegas.

Pacquiao has been away from action for over two years. His last fight took place in July 2019, when he picked up a twelve round unanimous decision over Keith Thurman.

He was initially scheduled to face WBC, IBF welterweight champion Errol Spence - but Spence was forced to withdraw with an eye injury that required immediate surgery.

Ugas was already a part of the undercard, as he was set to face Fabian Maidana in the co-feature. That fight also fell out when Maidana suffered a bad cut during sparring.

When the chance to face Pacquiao was offered - Ugas jumped on the opportunity.

A loss would certainly mark the end for Pacquiao's pro career that saw world titles in eight weight classes.

“I’m here to wreck any future plans Manny Pacquiao has in the ring and make sure that Saturday is his last fight," Ugas said.

“It feels great to be in the main event Saturday night against a true legend like Pacquiao. I can’t wait to get in the ring on Saturday night.

“I didn’t hesitate at all when I got offered this fight. I knew right away what a big opportunity it would be and what a win like this can do for my career.

“I always work hard and give it my all every day in training camp. We were already working for the Fabian Maidana fight. Of course, once I knew I was fighting Pacquiao, I was motivated even more, but I always give it my all in training camp.”
