For nearly a decade, the rivalry between Conor McGregor and Nate Diaz has existed in a strange state of unfinished business.
One fight each.
No resolution.
No trilogy.
Just years of tension, callouts, social media shots, and the lingering feeling that MMA’s most personal rivalry never truly ended.
Now, in 2026, the feud has exploded back to life.
And this time, the timing could not be more brutal.
On May 17, McGregor publicly mocked Diaz on social media just hours after Diaz suffered a bloody stoppage loss to Mike Perry in his return to MMA at Netflix’s MVP event in California.
McGregor’s message was vicious, personal, and unmistakably calculated.
“I see why Nate Diaz 209 didn’t take the fight lol. Anyway, here’s to when I get my hands on you, you lanky streak of piss. Trilogy and I’m gonna need my money.”
The tweet instantly detonated across combat sports.
Not just because of the insult itself.
But because of what was happening simultaneously elsewhere in MMA.
Only hours earlier, Dana White had officially confirmed McGregor’s UFC return against Max Holloway at UFC 329 in Las Vegas.
McGregor finally had his comeback fight.
And instead of focusing entirely on Holloway, he immediately turned his attention toward the one rival he has never fully escaped:
Nate Diaz.
Why Nate Diaz Still Haunts Conor McGregor
McGregor has had many rivals.
He knocked out José Aldo in 13 seconds.
He dismantled Eddie Alvarez to become a two-division champion.
He fought Dustin Poirier three times.
He battled Khabib Nurmagomedov in the biggest grudge match in UFC history.
But Diaz remains different.
Because Diaz is the only major rivalry McGregor never definitively closed.
At UFC 196, Diaz shocked the world by submitting McGregor and handing him his first UFC loss.
Five months later, McGregor narrowly won the rematch at UFC 202 by majority decision in one of the greatest fights in UFC history.
And then… nothing.
The trilogy never happened.
For ten years, the score has remained tied 1–1.
That unfinished tension has lingered over both careers ever since.
Every McGregor comeback eventually circles back to Diaz.
Every Diaz interview eventually circles back to McGregor.
No matter where their careers go, they keep orbiting each other.
Why McGregor Chose This Moment to Strike
The timing of McGregor’s tweet was surgical.
Diaz had just endured one of the bloodiest losses of his career.
Competing at Netflix’s first major MMA event under the MVP banner, Diaz returned to MMA for the first time in nearly four years against Mike Perry — a man rebuilt through years of brutal bare-knuckle fighting.
The fight was savage from the beginning.
Perry pressured relentlessly, throwing looping shots and vicious elbows inside the clinch. Diaz attempted to establish his jab and control distance, but the damage escalated quickly.
By the second round, Diaz’s face had become a wall of blood.
Cuts opened across his forehead and around his eyes. Blood poured into his vision. Every blink blurred red.
Finally, before the third round began, Diaz’s corner stopped the fight.
The official result:
Second-round TKO via doctor’s stoppage.
It was a brutal image:
Nate Diaz — battered, bleeding, and unable to continue.
And that was the exact moment McGregor decided to attack.
The implication behind McGregor’s tweet was clear:
Diaz avoided the trilogy because he knew he no longer had what it takes.
That Diaz saw McGregor’s comeback looming and chose not to be part of it.
But Diaz himself had already publicly explained why he turned the fight down.
And his reasoning tells a completely different story.
Nate Diaz Says He Refused to Be McGregor’s “Comeback Story”
Before facing Mike Perry, Diaz openly discussed why he rejected the UFC’s attempt to book him against McGregor.
Speaking with Ariel Helwani during fight week, Diaz made his position crystal clear.
“I know the UFC wanted the Conor fight right now. And I’m like, I’m not trying to be a comeback story for Conor.”
That quote completely reframes the narrative.
McGregor portrayed Diaz as scared.
Diaz portrayed himself as principled.
From Diaz’s perspective, the issue was not fear of fighting McGregor again.
It was timing.
McGregor had not fought since breaking his leg against Dustin Poirier at UFC 264 in 2021. After five years away from MMA, Diaz did not want to serve as the carefully selected comeback opponent designed to restore McGregor’s aura.
Diaz wanted McGregor to prove himself first.
Then they could settle the rivalry properly.
That distinction matters enormously.
Diaz was not avoiding the trilogy.
He was rejecting the role of sacrificial comeback opponent.
Nate Diaz Wanted Charles Oliveira Instead
Diaz also revealed that the fight he actually wanted was against Charles Oliveira.
According to Diaz, Oliveira declined.
What frustrated Diaz even more was that Oliveira later showed interest in fighting McGregor instead.
To Diaz, that represented everything wrong with modern fight matchmaking.
As Diaz explained:
“Why are you trying to fight the guy who’s coming off a leg break, just got knocked out, and he’s all messed up?”
That statement perfectly captures Diaz’s mentality.
He still views fighting through an old-school lens:
-
fight dangerous opponents,
-
fight active fighters,
-
fight men who have earned it.
In Diaz’s eyes, chasing McGregor immediately after a catastrophic injury and five-year layoff felt opportunistic.
So instead, Diaz chose Mike Perry.
And that decision came with consequences.
Mike Perry Was Never a Soft Fight
Some fighters returning after four years away would choose a favorable matchup.
Diaz deliberately did the opposite.
Perry had transformed himself through bare-knuckle boxing, becoming one of the most violent and durable fighters in combat sports. Years of fighting without gloves sharpened his inside game, especially his elbows and clinch striking.
Those skills became devastating against Diaz.
The cuts came early.
Then they multiplied.
Perry’s elbows carved Diaz open until blood completely overwhelmed the Stockton veteran’s vision.
Even so, Diaz refused to quit mentally.
Immediately after the stoppage, he demanded a rematch.
“I think I broke my finger in the first two seconds,” Diaz said afterward. “I’m gonna come back and get his ass. Ain’t nobody beating me twice.”
That response explains why Diaz still commands enormous respect despite losses.
He never retreats from violence.
He never hides.
And he never stops believing he can come back.
McGregor’s Tweet Was About More Than Mockery
On the surface, McGregor’s message looked like simple trash talk.
Underneath, it was business.
Because while McGregor publicly insulted Diaz, he also quietly did something else:
He reopened the trilogy narrative.
The hashtag “trilogy” in his post was not accidental.
Neither was “I’m gonna need my money.”
McGregor understands the economics of MMA better than almost anyone alive.
If he defeats Max Holloway at UFC 329, the demand for Diaz vs. McGregor 3 would become overwhelming.
No fight available to McGregor would generate:
-
more nostalgia,
-
more emotional investment,
-
more media attention,
-
or more money.
The rivalry still carries enormous cultural weight because it feels unresolved.
That unresolved tension is valuable.
McGregor knows it.
So even while preparing for Holloway, he is already planting the seeds for the next mega-fight.
Nate Diaz’s Response Was Pure Nate Diaz
Despite suffering a gruesome defeat, Diaz did not react emotionally to McGregor’s comments.
He didn’t explode.
He didn’t rant.
He didn’t spiral publicly.
Instead, after the fight, Diaz calmly spoke to the media about McGregor’s upcoming fight with Holloway.
His assessment was surprisingly respectful.
“It’s a rematch, right? Because Conor was taking him down the last time. So that’s gonna be a good fight.”
No bitterness.
No panic.
No attempt to scream louder than McGregor.
That reaction perfectly encapsulates why Diaz remains such a unique figure in MMA.
He has never tried to manufacture authenticity.
He simply is authentic.
Even bloodied and stitched together after a brutal stoppage loss, Diaz still carried himself exactly the same way he always has.
Calm.
Detached.
Unbothered.
The Trilogy Is Still the Biggest Fight Left
Right now, the future depends on two fights:
-
McGregor vs. Holloway at UFC 329
-
Diaz potentially rematching Mike Perry
If McGregor wins, momentum for Diaz vs. McGregor 3 will explode instantly.
And if Diaz avenges the Perry loss, the timing could become perfect.
Because despite everything that has happened over the last decade, the reality remains simple:
These two fighters still need each other.
McGregor needs Diaz because no rivalry defines his UFC legacy more completely.
Diaz needs McGregor because the trilogy would become the biggest payday and biggest spotlight of his career.
And fans need the trilogy because some stories simply should not end unfinished.
Why This Rivalry Refuses to Die
Most MMA rivalries eventually fade.
This one never has.
Maybe it’s because both men exposed something real in each other.
McGregor discovered vulnerability when Diaz submitted him.
Diaz discovered superstardom when he shocked the world.
Together, they changed each other’s careers forever.
That emotional connection still exists underneath every insult, every tweet, every interview, and every callout.
Which is why McGregor attacking Diaz after one of the worst nights of his career feels simultaneously cruel, strategic, and deeply personal.
And it’s why Diaz’s response — calm, stitched together, and almost indifferent — somehow made the rivalry feel alive all over again.
Right now, the trilogy still does not officially exist.
But after years of silence, false starts, injuries, and failed negotiations, something important changed this week:
For the first time in a long time, Conor McGregor and Nate Diaz are talking about each other again.
And in MMA, that usually means the story isn’t over yet.
