This Saturday at the MGM Grand in Las Vegas, the UFC will put on their very first all-heavyweight main card with UFC 146: Dos Santos vs. Mir.
The landmark fight card is to be headlined by a heavyweight title fight between champion Junior dos Santos and former champ Frank Mir. However, this wasn’t always the plan. Dos Santos was originally scheduled to take on Alistair Overeem in the main event, but Overeem registered an elevated testosterone-to-epitestosterone ratio and was unable to compete in the bout. Mir was pulled up from his planned co-main event fight against Cain Velasquez to challenge for the belt for a third time.
To promote the new main event, the UFC set up a Primetime special chronicling the two fighters’ lead-up to the fight. You can check out episodes one and two of UFC Primetime: Dos Santos vs. Mir below.
