Donald ‘Cowboy’ Cerrone has fed into the rumours of a stumbling block when it comes to a fight with Conor McGregor by claiming the former two-weight champion will only fight in a main event.

Earlier in the week, UFC commentator Joe Rogan had revealed on his podcast ‘The Joe Rogan Experience’ that he had heard that the UFC were struggling to set-up a fight with McGregor and Cerrone as the promotion would prefer to headline a PPV with a title fight.

Despite the Irishman currently holding the top three highest PPV buy rates in the UFC’s history, two of which coming against Nate Diaz in non-title fights, Cerrone recently spoke with ESPN where ‘Cowboy’ corroborated the hearsay.

“Conor won’t fight unless it’s a main event,” Cerrone said. “I don’t know if it’s an ego thing or a status thing for him. I don’t give a s***. I’ll fight anyone, anywhere, and I stand by that all the time. I guess he’s a prima donna and only takes main event spots. I don’t know.

“We were all waiting on Conor for April, and he said he wasn’t ready,” Cerrone continued. “I don’t know how in one breath you can say, ‘I’ll fight anyone, anytime, anywhere,’ and the next one say, ‘I’m not ready for that one.’

“I’m more annoyed that he went radio silent after putting it out. I get it, you want to stay relevant by putting it out there, but then you can’t go radio silent. Sack up, b****. Sign the f****** paper.”

Cerrone would go on to say that he has earmarked June 6th as the latest date for his next outing while UFC president Dana White recently revealed that the promotion was looking at a bout with the #4 ranked Al Iaquinta for Cerrone.

McGregor is currently suspended until April 6th for his part in the post-fight brawl at UFC 229 where he suffered a fourth-round submission loss to lightweight champion Khabib Nurmagomedov.
