Hall of Fame boxing commentator Bob Sheridan is giving WBA "regular" welterweight champion Lucas Matthysse a very good shot to pull off an upset win over eight division beltholder Manny Pacquiao.

Pacquiao, now 39-years-old, will challenge Matthysse on July 14th in Malaysia.

A loss would likely send Pacquiao straight into retirement - while Matthysse would get by far the biggest win of his pro career.

Pacquiao is already coming off a loss, and a stretch of inactivity, after losing a shocking twelve round unanimous decision to Jeff Horn in July 2017 at the Suncorp Stadium in Brisbane, Australia.

On the other hand, Matthysse  - who is now trained by respected coach Joel Diaz - is riding a hot streak in his career.

Matthysse is one of the biggest hitters in the sport, but at 35-years-old he is also nearing the final stage of his career.

Most experts are convinced that Pacquiao has clearly declined in his physical capabilities - and Sheridan is one of those experts.

He views this contest as being a very dangerous opportunity for the Filipino superstar.

"I think every fight is dangerous for Manny at this stage of his career. Manny has accomplished everything he can, he’s 39 years of age and that’s a problem. No matter how gifted an athlete you are and no matter how much you train, you’re not the same as when you were 29, and that’s the case with Manny Pacquiao," Sheridan told On The Ropes Boxing Radio.

"Horn was the first one to expose him, even though he had a decent fight against Horn and it was a close fight throughout, Horn exposed him. Matthysse has the powerful right and if Manny gets caught, he’ll go, and that’s all there is about it. Every fight at this stage is dangerous when you’re fighting a world class fighter like Matthysse. It’s a dangerous fight."
