Years later, he got the opportunity to redeem himself when he earned a rematch against Mir at UFC 140.
Nogueira looked like he was on his way to get redemption. 'Big Nog' tagged Mir with elbow strikes and dropped him with some stinging punches. Nogueira pounded away as Mir tried to recover. Just as Mir appeared to be a few shots away from being stopped, Nogueira decided to lock in a guillotine choke.
It proved to be a costly mistake as Mir caught Nogueira's right arm in a kimura during a scramble. With Nogueira refusing to tap, Mir cranked as hard as he could until his opponent's arm broke.
After the fight, the Brazilian said he wanted a beautiful submission win so he went for the choke instead of just throwing a few more strikes. However, he retracted the statement a week later and it was referee Herb Dean's fault as he instructed Nogueira not to hit the back of the head.
#3. Alistair Overeem insists that Stipe Miocic tapped (UFC 203)
After going through a stretch of inconsistency at the beginning of his UFC career, Alistair Overeem finally earned a title shot against Stipe Miocic at UFC 203.
In one of the most action-packed single-round bouts in the promotion's history, Overeem came very close to capturing the most prestigious title in mixed martial arts. 'The Demolition Man' dropped Miocic with a straight left and proceeded to lock in a guillotine choke.
The champion displayed composure as he was able to survive the submission attempt and get back up quickly. Shortly thereafter, momentum shifted when Miocic successfully took the challenger to the ground and rained punches down to secure the TKO victory.
During the post-fight interview, Overeem insisted that he let go of the chokehold because he felt the champion tap. But things went from bad to worse for Overeem when Joe Rogan asked for the replay.
After reviewing the tape, it became apparent that Miocic did not even come close to tapping and Overeem was caught in a lie. The champion's hometown of Cleveland, Ohio showered the Dutchman with boos as he made his way out of the octagon.
