Joe Rogan was replaced by Paul 'The Irish Dragon' Felder who handled one half of the color commentary alongside play-by-play man Jon Anik and fellow fighter-turned-analyst Daniel Cormier.

Rogan along with many UFC fans and fighters say that Petr Yan was 'robbed' by the judges in his split decision defeat by Sean O'Malley at UFC 280.

The bantamweight duo put on an incredible showing but there was almost universal agreement that the Russian had done enough to win on the scorecards. However, when the result was revealed in the octagon by Bruce Buffer, O'Malley was given the nod.
