stated, that in his opinion, holding victories over former UFC Interim Heavyweight Champion Antônio Rodrigo Nogueira at UFC 92 and current UFC Heavyweight Champion Brock Lesnar at UFC 81 is enough to recognize him as the owner of the "real belt." Mir was originally scheduled to fight Lesnar at UFC 98 On May 23, 2009, in Las Vegas, Nevada, however, he sustained a knee injury during training which required arthroscopic surgery and the removal of bone chips from his knee. The rematch against Lesnar was therefore rescheduled for UFC 100 on July 11, 2009. The show would break many UFC records in terms of PPV sales and is in the top 3 best selling UFC PPV of all time.

During the fight, Mir stunned Kongo with an overhand left early, dropping him and swarming to secure a guillotine choke victory at 1:12 in the first round. Kongo refused to tap and was rendered unconscious by the choke. In the post-fight press conference, Mir expressed his desire to fight a rubber match with Brock Lesnar. Mir later created controversy after commenting that he
