5 UFC rematches that would be much bigger the second time around

#2. Carla Esparza vs. Joanna Jedrzejczyk - UFC women's strawweight division

Esparza and Jedrzejczyk have a combined record of 16-7 since their first fight

These two female athletes fought for the UFC women's strawweight title back in March 2015. On that day, Carla Esparza came into the bout having just defeated Rose Namajunas to win the gold. However, Joanna Jedrzejczyk defeated her to become the new champion. Could history now be repeating itself?

Esparza recently defeated Namajunas for a second time to begin a second stint as the strawweight champion. Should Jedrzejczyk defeat Weili Zhang on June 11, she would become the No.1-contender to challenge for the title. Given all that's happened since their first fight, a rematch would inevitably be a bigger deal.

Since 2015, Jedrzejczyk became the longest-reigning champion in the division's history, and more recently, took part in the best women's MMA fight ever. Esparza has fought 12 times in the meantime and is now back atop the division. There is now a good chance we could get a highly anticipated rematch before too long.

#1. Conor McGregor vs. Max Holloway - UFC lightweight division

McGregor and Holloway have gone 24-7 since their first fight

Few would have known when these men first fought back in August 2013, that they would go on to become two of the biggest stars the sport of MMA has ever seen. Both Conor McGregor and Max Holloway would go on to win the UFC featherweight championship, with the Irishman also winning the lightweight title.

In their first fight, McGregor had a promotional record of 1-0 and Holloway's octagon record was 3-2. Those records now stand at 10-4 and 19-6 respectively, with both men taking on some of the biggest names in the sport. They are now true megastars in the sport and a rematch would be truly monumental.

This is a fight that wouldn't require a title on the line and it would still likely be the biggest PPV the UFC can put on that year. It is now a dream fight for MMA fans despite their first encounter flying somewhat under the radar. With both fighters being so popular, a rematch could well happen before the end of their careers.
