UFC 220 is estimated at doing 340,000 to 380,000 pay-per-view buys, numbers in line with the UFC show three weeks earlier.
The major hook on the show was the promotion of Francis Ngannou as a knockout artist going for the UFC heavyweight title against champion Stipe Miocic, who also had a string of impressive knockouts to his credit. Ngannou was riding momentum of one of the most memorable knockouts in recent years against Alistair Overeem.
The show also featured a second championship match, the light heavyweight title, with Daniel Cormier retaining over Volkan Oezdemir.
