5 times UFC champions showed tremendous heart to survive and came back to win

#4. UFC 154: Georges St-Pierre vs. Carlos Condit

The UFC welterweight headliner between Georges St-Pierre and Carlos Condit took place in the champion's backyard of Quebec. The pay-per-view was hosted at the Bell Centre in Montreal, Quebec, in November 2012. GSP's fight against Condit, by his own admission, marked the proudest moment of his career.

Over the course of GSP's lengthy injury-induced layoff, Carlos Condit had solidified himself as the interim champion. The title unification bout was a hard-fought fight between the two fighters.

However, the third round of the fight witnessed St-Pierre on the receiving end of a well-struck head kick that rocked him. It seemed 'The Natural Born Killer' was only moments away from sealing the victory.

GSP showed the heart of a champion and mounted an inspiring comeback, dominating Condit for the remainder of the fight. He went on to secure a unanimous decision win.

#3. UFC 152: Jon Jones vs. Vitor Belfort

Headlining the UFC 152 event, Jon Jones and Vitor Belfort went toe-to-toe against each other in September 2012. The fight took place at the Scotiabank Arena in Ontario, Canada. 'Bones' started his title defense against an aging Belfort rather strongly.

However, he suffered a significant setback right in the first round of the fight. Shortly after the first bell, Belfort caught Jones in a dreadful armbar that had Jones wincing in pain.

Vitor Belfort's triumph was relatively short-lived as Jones soon broke free and dominated the challenger for the remainder of the fight. He subsequently locked in a fierce Americana submission, forcing Belfort to tap out within the first minute of the fourth round.

Jones, in the aftermath of his battle against Belfort, was seen in a sling. It was later revealed that he had suffered a strained ligament in his arm.
