Alex Pereira’s recent successful defense of his light heavyweight title at UFC 303 has added the Brazilian’s name to the ever-growing list of fighters who have successfully changed weight divisions within the UFC.
Today we take a look at some of the most notable examples (along with a few that didn’t fare quite as well).
CONOR McGREGOR
The original ‘champ-champ’. The first man to simultaneously hold championship belts in two different weight divisions. “The Notorious” signed with the UFC back in 2013 having won both the featherweight and lightweight titles in Cage Warriors and within two-and-a-half years he knocked out Jose Aldo to claim the 145-pound belt.
Less than a year later, he put on perhaps the best display of his career when he beat Eddie Alvarez at the iconic Madison Square Garden to claim the 155-pound strap. He has also competed in the welterweight division, fighting Nate Diaz twice and Donald Cerrone. His recent (now postponed) comeback bout against Michael Chandler had been set to take place over five rounds at 170 pounds.
DANIEL CORMIER
“DC” enjoyed huge success fighting as a heavyweight prior to signing with the UFC in 2013. He beat Antonio “Big Foot” Silva and Josh Barnett to win the Strikeforce heavyweight grand prix in 2012 and began his UFC career with wins over former heavyweight champion Frank Mir and Roy Nelson, before making the decision to move down to 205 pounds as his teammate Cain Velazquez was the heavyweight champion at the time.
Cormier submitted Anthony “Rumble” Johnson in 2015 to claim the vacant light heavyweight title, and three years later, he made the decision to move up and challenge then-champion Stipe Miocic for the heavyweight title. He shocked the world by knocking out Miocic in the first round, although the Cleveland-born firefighter gained his revenge by beating Cormier twice in 2019/2020, retiring him from the sport.
ROBERT WHITTAKER
“Bobby Knuckles” signed with the UFC back in 2012 off the back of some impressive performances on The Ultimate Fighter: The Smashes and had mixed results during his time competing in the welterweight division. He won three of his first five fights, but losses to Court McGee and Stephen “Wonderboy” Thompson convinced Whittaker to test the waters at 185 pounds.
What followed was an eight-fight winning streak, wins over the likes of Yoel Romero and “Jacare” Souza and the UFC middleweight title. Whittaker lost the belt to Israel Adesanya in 2022 but is still riding high in the division and finds himself in the title picture once again after his recent knockout victory over Ikram Aliskerov.
HENRY CEJUDO
The 2008 Olympic gold medalist won his first four fights inside the Octagon to earn a shot at then-UFC flyweight champion Demetrious “Mighty Mouse” Johnson back in 2016. Although Cejudo was knocked out in the first round, he soon worked his way back into title contention with some impressive victories over Wilson Reis and Sergio Pettis.
The rematch was a much closer affair, and “Triple C” ended Johnson’s record-breaking title reign and emerged victorious by way of a contentious split decision. A year later he moved up to 135lbs to challenge Marlon Moraes for the vacant UFC bantamweight title. He finished Moraes and then beat former champion Dominick Cruz in his first title defence in 2020, before relinquishing his belt and announcing his retirement, in what seemed like a power play due to contract issues with the UFC.
Cejudo returned to competitive action in May of 2023 but defeats to Aljamain Sterling and Merab Dvalishvili have left him further away from title contention than he has been in a long time.
3 Fighters Who Moved Down A Weight Division…With Disastrous Results!
TJ DILLASHAW
TJ Dillashaw enjoyed two separate runs as UFC bantamweight champion. He shocked the MMA world when he destroyed Renan Barao at UFC 173 to capture the 135-pound belt. After losing the title to Dominck Cruz two years later, he regrouped and beat Raphael Assuncao and John Lineker to earn another shot at gold.
He knocked out former teammate Cody Garbrandt (who had won the belt from Cruz a year earlier), and after finishing “No Love” again in a rematch, made the decision to cut to 125 pounds to challenge Henry Cejudo for the flyweight title.
The decision proved disastrous. Dillashaw was knocked out after just 32 seconds, and a couple of months later it was announced he had been suspended for two years by USADA due to testing positive for EPO in the lead-up to the Cejudo fight.
He returned after his suspension ended and beat Cory Sandhagen to earn another shot at the 135-pound belt but went into the fight against Aljamain Sterling carrying a serious shoulder injury and was finished easily. He has since walked away from the sport.
CODY GARBRANDT
Cody Garbrandt came into that first bantamweight title fight with TJ Dillashaw unbeaten at 10-0 and riding high off the back of a career-best performance against Dominick Cruz. The two losses he suffered at the hands of Dillashaw seemed to affect him badly. He was also knocked out by Pedro Munhoz in his next fight, and although he would claim a highlight reel finish over Raphael Assuncao in 2020, a defeat to Rob Font soon afterwards convinced him a change was needed.
With no discernible path back into the bantamweight picture, “No Love” decided to make the cut to 125 pounds for a fight against Australian flyweight contender Kai Kara-France at UFC 269. Another first-round knockout defeat followed, and Garbrandt stepped away from the spotlight for a much-needed break.
His return to the bantamweight division has been a little less calamitous. Wins over Trevin Jones and Brian Kelleher, followed by a submission loss to Deiveson Figueiredo at UFC 300, have hinted that perhaps his future lies slightly outside of the title picture for now, but most definitely should be at 135 pounds.
DAN HOOKER
“The Hangman” picked up a string of impressive wins in the UFC’s lightweight division between 2017 and 2021, beating the likes of Paul Felder, Al Iaquinta, Gilbert Burns, and Jim Miller. His record at 155 pounds during that five-year spell sits at eight wins and four defeats, but losses against the biggest names in the division such as Michael Chandler, Dustin Poirier and Islam Makhachev convinced the Australian to think about a move down to featherweight.
His featherweight debut against Arnold Allen in London, England ended disastrously. At six-feet tall, Hooker looked frail and weakened at 145 pounds and Allen destroyed him in little over two minutes. Hooker has since returned to the lightweight division and reeled off victories over Claudio Puelles and Jalin Turner.
One thing we know for certain: finding the right weight class is of paramount importance for a fighter. It can be the defining factor between a promising career and a championship legacy in the highly demanding world of the UFC.
