UFC 188: Velasquez vs. Werdum

The event was headlined by a Heavyweight Championship unification bout between Cain Velasquez and interim champion Fabrício Werdum, with Velasquez returning from a long layoff to fight at altitude in Mexico City. Velasquez had long been known for his cardio, but this time, it was Werdum who outpressured Velasquez. Werdum submitted Velasquez in the third round to become undisputed champion, closing one of the most dominant heavyweight runs of the era.
