Hours before Conor McGregor and Jose Aldo entered the Octagon to battle the for undisputed UFC featherweight championship in Las Vegas, heavyweight kingpin Fabricio Werdum told the media at the MGM Grand Garden Arena that "The Notorious’" team reached out to Rafael Cordeiro to train at Kings MMA for a few days.

"Conor McGregor wanted to train with us there," Werdum said in a media scrum. "No way. Imagine us against Jose Aldo, our friend? We're 100 percent with Aldo, the entire Kings MMA. There was a moment when someone said 'Well, Conor wants to train with you'. I had no answer.

"His manager asked Rafael, and master closed (the door) right away. No way he would train with us here. If he came, it would be to train with us for a few days, and yes, 100 percent, he wouldn't be able to fight. It would be dangerous because we would break him."

Rafael dos Anjos, who trains with Werdum at Kings MMA, also confirmed the story in a media day. However, McGregor’s manager Audie Attar refuted the claims.

"That is not true," Attar told MMAFighting.com. "Only contact we ever made to Kings was someone from my office had called there to see if Uriah Hall can train there, but no one called us back on Uriah. Never would've or could've called for Conor as he doesn't train with anyone else other than his coach John Kavanagh and his own teammates he brings in. He keeps his circle small, so this is someone making things up and feeding lies to Werdum. Kings is down the street from our offices in Orange County and I have the utmost respect for Rafael and that camp, but this just isn't true."

McGregor (19-2) defeated Aldo in 13 seconds to become the undisputed champion on Dec. 12, improving to 7-0 with six knockouts under the UFC banner. After unifying the 145-pound belt, "The Notorious" might move up and fight for the lightweight title against the winner of Saturday’s UFC on FOX 17 main event between Kings MMA’s Rafael dos Anjos and Donald Cerrone.
