Chael Sonnen has given a damning verdict on the fighting future of Conor McGregor, with the former two-division UFC title challenger saying that the Irishman shouldn't be booked, or sanctioned, to fight again in the UFC.

"The basic rule is protect yourself at all times. Conor McGregor is not in a position with anybody under contract with the UFC to protect himself at all times. It's a silly proposition. If you're talking about any level of responsibility, you can't book him, and you definitely can't book him in a five-round fight. That's insane."

Former UFC title challenger, commentator and podcaster Chael Sonnen doesn't think Conor McGregor will ever fight again and explained why.
