UFC 309: Jones vs Miocic

This event was built around Jon Jones vs. Stipe Miocic for the UFC Heavyweight Championship, with Charles Oliveira vs. Michael Chandler 2 as a five-round Lightweight co-main event. The main event was supposed to happen a year earlier, but a torn bicep forced Jones to pull out. During fight week it was announced that the UFC would bring back its previous glove design after complaints about the newer model. Miocic would retire in the Octagon, and Dana White would later announce Jones' retirement as well.
