O'Malley said on The Pat McAfee Show:

"Conor [McGregor] messaged me on Instagram for the first time yesterday. He said, 'Baby we did it,' and I said, 'We sure fu**ing did.' I said, 'You main eventing in December, I'm co-main eventing?'

#2. Former UFC champion Francis Ngannou pushed to the limit by Mike Tyson

Former UFC heavyweight champion Francis Ngannou is set to take on heavyweight boxing's greatest challenge right now, Tyson Fury. The pair will face off in the ring in a superfight later this year, and ahead of the clash, Ngannou has enlisted the help of boxing Hall of Famer Mike Tyson.

Tyson was captured talking about the grueling training regimen that he had planned for 'The Predator'. He said:

"[Francis Ngannou] had many professional fights, you know he just never experienced a professional boxing match. I was speaking to him once he came in and I asked him, 'Are you sore today?' And he said, 'No.' That was a big mistake."
