Conor McGregor announced his octagon return against Michael Chandler, but according the former two-division world champ, it will not be happening at UFC 300 as many were predicting. With the UFC's 2024 calendar filling up rapidly, what fight will headline one of the promotion's biggest and monumental events?

On an all-new edition of Heck of a Morning, MMA Fighting's Mike Heck reacts to the McGregor vs. Chandler announcement for June 29, if it is a mistake by the UFC to not have the fight headline UFC 300, and what the UFC could do in order to make that all-important main event spot pop. Additionally, listener topics include a potential Leon Edwards vs. Belal Muhammad fight, if Justin Gaethje or Charles Oliveira should get the shot at Islam Makhachev, the UFC's future at the APEX, the promotion's debut in Saudi Arabia still without a headliner, and much more.

You can listen live to Heck of a Morning Tuesdays, Thursdays, and Fridays at 10 a.m. ET on the MMA Fighting Twitter Spaces.
