Conor McGregor: From O-Rings to the boxing ring

Conor McGregor: From O-Rings to the boxing ring

The retired boxing superstar-turned-promoter unleashed his anger toward Floyd Mayweather Jr. and Conor McGregor in a profane Tweet sent out Friday afternoon, just after the weigh-in for the fight his company is promoting Saturday night, Miguel Cotto versus Yoshihiro Kamegai.

"Forty-nine times I went out there, it was one on one". Pending how long these fights last, the Mayweather-McGregor Fight should begin around 9 p.m.

The only way people are not going to feel ripped off is if there is some drama, instead of Mayweather slowly but surely busting up McGregor, while McGregor swings and misses. The building appeared to be essentially full, but that might not be the case on fight night: Ticket prices for Saturday's show are trending down, with many below the original list price.

While the public definitely likes the brash Irishman to pull off the upset this Saturday at T-Mobile Arena in Las Vegas, the value on Mayweather only seems to be increasing.

Mayweather, of Las Vegas, was a boxing champion in five weight classes, is 49-0, tied with legendary heavyweight champion Rocky Marciano's undefeated record. Mayweather, as you'd expect, was ready with a counter. His combination of speed and footwork, against a fighter who can't use most of his MMA weapons, likely will make for a typical Mayweather fight once the bells rings.

"He looks like dog [expletive]", McGregor said.

Even the cheapest $500 (£390) tickets are selling for as much as $1,300 (£1,015) on resale sites.

The 40-year-old Mayweather has repeatedly insisted this will be the final fight of his decorated career, and has made little secret of the fact he is looking forward to retirement.

The 29-year-old remains a significant underdog against a fighter widely considered the finest of the modern era, and having not concentrated on boxing since his teens.

"Paulie has always been my friend", Mayweather said.

Hardy said ultimately it's Mayweather's fight to lose.

"I gave my word to my children and once I did that it came to an end", Mayweather said. You know what I mean? "McGregor's going to get mugged".

Quigley also said he wanted to talk again after the fight, apparently to explain why he was making that prediction.

It all boiled over earlier this week when Malignaggi confronted McGregor during his arrival to the MGM Grand for a media obligation leading up to the fight.

Stephen Espinoza, the head of cable network Showtime Sports which is selling the fight on pay-per-view in the USA, said surveys had shown that fans were not deterred by predictions of a mismatch.
