Former UFC champion Vitor Belfort is pumped for his upcoming exhibition boxing match with six division world champion Oscar De La Hoya.

A few days ago, it was officially announced that Belfort was finalized as De La Hoya's comeback opponent for September 11 in Las Vegas.

The fight will headline a Triller Fight Club pay-per-view event.

De La Hoya has been out of the ring since 2008, when he suffered a one-sided stoppage loss at the hands of Manny Pacquiao.

His comeback has been rumored for years, but nobody ever thought he was going to actually come back. 

Belfort has actual boxing experience, with a single pro fight taking place back in 2006 - which he won with a first round knockout. That bout was expected to begin his career in boxing, but the lure of big paydays sent him right back to MMA. 

“I believe this fight with me and Oscar, this is the biggest fight ever. The reason why is Oscar is a legendary [Olympic] gold medalist, one of the best pound-for-pound that ever lived. He revolutionized the sport. If it wasn’t for Oscar, there wouldn’t be Mayweather. If it wasn’t for Vitor Belfort, Conor McGregor wouldn’t exist," Belfort said to TMZ.

So now the new generation will be educated on who these two guys are from Mexico and Brazil going to America, the land of the dreams. Oscar became an Olympic gold medalist. Vitor became the youngest (UFC) champion ever. This fight is about breaking records."

Belfort expects the contest to be a big hit on pay-per-view.

“Fights have always been, ‘Oh, this is the bad guy, this is the good guy.’ This fight will sell like Muhammad Ali and George Foreman because of skills, legacy. It’s because they paved the way for this generation today," Belfort said.
