CONOR McGREGOR lost $500,000 in just three minutes after backing Francis Ngannou to LOSE his MMA return.
Ngannou made his cage comeback after two years away against 6ft 8in Brazilian Renan Ferreira in Saudi Arabia.
And it came just seven months after he was brutally knocked out in the boxing ring by Anthony Joshua in two rounds.
McGregor whacked a huge $500,000 (£380,000) on Ferreira and said: “Hello, folks, The Notorious Conor McGregor here.
“Fight night, fight night, fight night… the Mac is back with his winning bets.
“I have a 100 per cent winning ratio on these bet. Ngannou is losing by KO tonight.
“12/5 the Brazilian is to knock him out and I’m putting half a million on it and I’m going to win back $1.7million. That’s it.
“It’s a ruthless business and I’m a ruthless man.”
But despite McGregor’s hot-streak, it came to a crashing end in just a round.
Ngannou, 38, took Ferreira, 34, down before hammering him with vicious ground and pound till the referee had seen enough.

It sealed a successful return to MMA for Ngannou and got him off to winning ways under the Professional Fighters League.
And it was also Ngannou’s first fight and victory since the tragic death of his 15-month-old son Kobe.
He tearfully dedicated the win to Kobe and said: “I can’t think about anything other than my son, Kobe.
“I only took this fight because of him, I took the fight for him. I hope they can remember his name because without Kobe, we wouldn’t be here tonight. I wouldn’t have fought.”
