5 UFC rematches that need to happen

#3 Tyron Woodley vs. Kelvin Gastelum

Kelvin Gastelum is an incredible finisher

Back in 2015, Tyron Woodley fought Kelvin Gastelum to a razor-thin split-decision win. Although Woodley came out the victor, the man clearly faced issues with Gastelum's boxing and distance control over the course of the fight.

In fact, Woodley is also said to have injured his foot during the bout, which in turn hampered his movement during the 3-round bout. Following that fight, Woodley went on to become the UFC Welterweight Champion and has enjoyed a decent title reign thus far. Meanwhile, Gastelum moved up to Middleweight and found great success there.

So much so, that Gastelum is now set to fight Robert Whittaker for the latter's UFC Middleweight Title this year. Gastelum has often spoken about wanting to run back his fight with Woodley, particularly because he feels he won their first fight, and if it weren't for his terrible weight cut before the fight, he'd have absolutely dominated Woodley.

Moreover, Woodley has spoken about wanting to move up to challenge the Middleweight Champion, and should Gastelum beat Whittaker for the Middleweight Title; we could very well get to see Woodley vs. Gastelum 2 at 185 pounds instead of 170 pounds.

This is a very important fight for both fighters, as a significant amount of interest has been shown by the duo in fighting each other one more time.
