The Justin Gaethje vs. Conor McGregor matchup has taken another interesting turn. What was once a hypothetical fight now has a more realistic storyline behind it, with Gaethje sitting atop the UFC lightweight division and openly mentioning McGregor as a potential opponent.
Gaethje recently suggested that fighting McGregor would be a fun option, even though it would mean passing on opportunities to avenge losses to former opponents Charles Oliveira and Max Holloway. The comments have added fresh fuel to one of MMA's most intriguing potential matchups.
The biggest change since the original discussion around a Gaethje-McGregor fight is Gaethje's position in the lightweight division.
Gaethje defeated Paddy Pimblett by unanimous decision at UFC 324 in January 2026 to capture the interim lightweight championship. He then faced the previously undefeated Ilia Topuria at UFC Freedom 250 on June 14 and produced one of the biggest wins of his career, stopping Topuria by corner stoppage at the end of the fourth round.
That victory finally gave Gaethje undisputed UFC lightweight gold after previous championship defeats against Khabib Nurmagomedov and Charles Oliveira. The UFC currently lists his professional record at 28-5-0, with 21 wins by knockout.
Gaethje's status as champion makes a potential McGregor fight considerably more interesting from a commercial standpoint. Instead of being another contender looking for a major payday, Gaethje now controls one of the most valuable positions in the UFC.
Gaethje has previously made no secret of his interest in fighting McGregor. In June, shortly after winning the lightweight championship, he said he would love to punch McGregor in the face and acknowledged the financial and legacy benefits of facing one of MMA's biggest stars.
More recently, Gaethje went a step further when discussing potential opponents for his first title defense.
Rather than immediately targeting Oliveira or Holloway, two fighters who have previously defeated him, Gaethje joked that Topuria's victories over both men were enough for him to consider those losses avenged. That left McGregor as an attractive alternative.
Gaethje's reasoning was straightforward: a fight with McGregor would be entertaining, financially significant, and personally satisfying.
He also acknowledged that his position has changed now that he is champion. Instead of chasing the belt, Gaethje is now the fighter everyone else is trying to catch.
McGregor's situation has also changed dramatically.
The former two-division champion finally returned to the UFC in July 2026 after more than five years away from competition. His comeback came against Max Holloway at UFC 329 in a welterweight rematch of their 2013 fight.
However, the comeback lasted only moments before McGregor suffered a serious leg injury. Holloway was awarded a TKO victory after the fight was stopped, ending McGregor's long-awaited return disappointingly.
McGregor had not competed since suffering a broken leg against Dustin Poirier at UFC 264 in July 2021. His latest injury now creates another major question surrounding his future.
That uncertainty is important when discussing Gaethje. There is currently no confirmed Gaethje-McGregor fight, and McGregor would first have to recover sufficiently before returning to competition.
From a rankings perspective, McGregor would not necessarily be the obvious choice for Gaethje's first title defense. The lightweight division has several legitimate contenders, including Arman Tsarukyan and other top-ranked fighters waiting for opportunities.
But MMA isn't decided by rankings alone.
McGregor remains one of the biggest commercial attractions in combat sports. A championship fight against Gaethje would combine McGregor's enormous profile with Gaethje's status as one of the division's most dangerous and established fighters.
Stylistically, the matchup would also be fascinating.
Gaethje is known for relentless pressure, powerful leg kicks, heavy combinations, and a willingness to engage in prolonged striking exchanges. McGregor, meanwhile, has traditionally relied on timing, distance management, counterpunching, and his dangerous left hand.
The biggest question would be whether McGregor could handle Gaethje's pressure and leg kicks over the course of a championship fight, particularly after his lengthy layoffs and recent injury problems.
The biggest obstacle is timing.
Gaethje recently confirmed that he expects to remain out of action until 2027 while recovering from hand injuries sustained during his fights earlier this year. He said he plans to use the remainder of 2026 to recover and consider his future.
That gives the UFC plenty of time to determine the lightweight title picture.
Arman Tsarukyan is scheduled to face Mauricio Ruffy at UFC 331 on September 19, with the result potentially influencing the next title challenger. Gaethje has acknowledged that upcoming fights could help determine who eventually gets the championship opportunity.
For that reason, Gaethje vs. McGregor is possible, but far from guaranteed.
Justin Gaethje is no longer simply interested in fighting Conor McGregor someday. He is now the undisputed UFC lightweight champion and has specifically mentioned McGregor as a fight he would entertain.
At the same time, McGregor's future is uncertain following his injury-shortened UFC 329 comeback. Gaethje is also expected to remain sidelined until 2027, giving the UFC time to see how the lightweight division develops.
If both men eventually return healthy and the UFC decides that the commercial opportunity outweighs the rankings argument, Gaethje vs. McGregor could become one of the biggest lightweight fights available.
For now, however, it remains a compelling possibility rather than a confirmed matchup.

Conor McGregor's UFC Return Did Not Go as Planned

Why Gaethje vs. McGregor Still Makes Sense
