From the moment the contest was announced, Golden Boy Promotions CEO Oscar De La Hoya was a big critics of the crossover showdown between the comebacking Floyd Mayweather Jr. and UFC superstar Conor McGregor, which took place last Saturday night at the T-Mobile Arena in Las Vegas.

McGregor, who was making his professional boxing debut, started strong in the early round - faded as the fight continued - and was stopped in the tenth round round.

De La Hoya felt the Showtime Pay-Per-View, which had a high price tag of $100 for HD, was a scam because McGregor had no boxing experience and was facing one of the best defensive fighters in boxing history.

Last Friday, a day before the contest took place, De La Hoya took to social media and gave a big "f* you" to the Mayweather-McGregor pay-per-view and said both fighters were disrespecting boxing by going forward with this fight.

De La Hoya explained that he was simply tired of fans paying money to watch Mayweather in pay-per-view bouts where the opponents had no chance of winning.

"Of course [I was mad], because I was defending the sport of boxing. This fight, Mayweather vs. McGregor, was a form of a scam and fraud. Mayweather, for the first four rounds, didn't do anything. When has Mayweather not done anything for the first four rounds? And ironically the fight gets stopped in the tenth round and reports are that Mayweather bet on himself in the tenth round. This is what people were suckered into. I just want to tell people that this is what Mayweather is and I'm tired of it," De La Hoya told Chris Mannix of The Dan Patrick show.

De La Hoya doubts the contest will do any damage to the sport of boxing - because the Golden CEO has a major pay-per-view of his own coming up - when Mexican superstar Saul "Canelo" Alvarez challenges IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin, also at the T-Mobile.

"I don't think it will [hurt boxing], because we have this great, great fight coming up with Canelo and Triple G. I just feel bad for the fans who paid their hard earned money for it - that's all. A lot of people were telling me at the StubHub Center, where we were promoting Cotto, which by the way was a sell-out, that they were really disappointed [with Mayweather-McGregor] but they were happy because coming up was Canelo and Triple G," De La Hoya said.
