UFC 264: Everything you need to know about Conor McGregor vs. Dustin Poirier 3

Cormier details Poirier's KO of McGregor (1:38)

Daniel Cormier breaks down Dustin Poirier's most effective strikes vs. Conor McGregor in UFC 257. Watch the full episode on ESPN+. (1:38)

The UFC 264 main event between Conor McGregor and Dustin Poirier won't have a title on the line, but there will be plenty at stake on Saturday before a capacity crowd at T-Mobile Arena in Las Vegas.

And the significance goes deeper than the winner likely landing a title shot against lightweight champ Charles Oliveira.

For Poirier, the decision to face McGregor for a third time meant passing up the opportunity to fight for the title vacated by the retirement of Khabib Nurmagomedov. Poirier has held the interim belt before, but being undisputed champ is the dream of every fighter. Poirier is betting on himself, confident he'll beat McGregor again in what should be the most lucrative fight of his career. The plan is to win the money fight first and then go after the title fight. A loss would put his title quest on an uncertain path.

For McGregor, he's trying for his first win over an elite opponent since he beat Eddie Alvarez in 2016. Once considered one of the top pound-for-pound fighters in the world, McGregor now just hopes to silence the critics who suggest he lost his mojo after attaining incredible wealth. Can McGregor regain his championship form? That's a huge part of the backdrop for this blockbuster. And the reality is, despite McGregor's recent plight, he could very well land the title shot with a victory.

For now, it's about the trilogy. McGregor KO'd Poirier in less than two minutes in 2014 as his star ascended to unprecedented heights, and Poirier avenged the loss on Jan. 23 with a second-round KO.

Keep checking back, as this story will be updated with news, features, videos and social media observations as one of the most anticipated trilogies in combat sports history approaches its completion.

One win in nearly five years: What's gone missing for Conor McGregor?

Conor McGregor's rise was unlike anything witnessed before in MMA. In his first 10 UFC fights, McGregor went 9-1 with seven knockouts and a UFC-record -- since tied by Justin Gaethje -- nine bonuses. He became the first UFC fighter to hold belts in two weight classes at the same time. Along the way, he became the greatest pay-per-view attraction and ticket-selling draw in UFC history.

On Saturday, McGregor faces a defining point in his career when he and Dustin Poirier complete their trilogy in the main event of UFC 264 in Las Vegas. Since that record-setting start, McGregor is just 1-2 -- his only victory against a past-his-prime Donald "Cowboy" Cerrone -- in nearly five years.

Show me the money -- Inside Dustin Poirier's risk in taking the Conor McGregor payday

BOCA RATON, Fla. -- It's 2 p.m. on a Wednesday, and Dustin Poirier is methodically wrapping his hands at an empty boxing gym owned by his longtime coach, Dyah Davis. He is 17 days out from his lightweight trilogy fight against Conor McGregor in the main event of UFC 264, and though his mood seems fine, he's tired.

"I haven't had two consecutive days off in nine weeks," he tells Davis, who seems to sympathize but doesn't offer to shorten the session.

Soon enough, a bell on Davis' phone signals Poirier to get to work. "Fine," Poirier says. "I'll take a break when I knock this motherf---er out."

Best bets for UFC 264: Conor McGregor vs. Dustin Poirier 3

With odds that have floated for months, the market still hasn't really taken a significant side in this one. McGregor's odds have historically seemed inflated due to his popularity, and in this space nearly six months ago, we took the underdog value on Poirier. Now, with the benefit of having seen them fight for seven and half minutes, the once long odds on Poirier have drawn close to even. With such affordable odds, we're left with a simple question: Who has the better chance to win?

Wagenheim: McGregor talked his way to the top of the UFC, but has he lost his edge?

As Poirier and McGregor prepare to complete their trilogy on Saturday at UFC 264 in Las Vegas, the question lingers about whether McGregor still has it in him to defeat an opponent before the first punch is thrown. There has been a bit of acrimony flung back and forth this time around, but it was initiated by Poirier, who chided McGregor for not having followed through on a pledge to donate to Poirier's charity.

McGregor responded with vitriol and with a donation -- to a different charity in Poirier's hometown.

Then, on Tuesday, McGregor posted a voice message with a couple of insults and said he was coming for Poirier. He later tweeted what appeared to be a direct message request from Poirier's wife, Jolie. There were no accompanying words from McGregor, just insinuation. Dragging family into the trash talk is a low blow, and both that and the voice message seem more like acts of a desperate man than masterful head games. But we'll see on Saturday.

No title at stake, but McGregor's legacy will be on the line

Let me tell you why there is so much riding on this trilogy fight -- it's not outlandish to say that the entire narrative of McGregor's athletic career could be on the line.

As of this moment, what would we say about McGregor the fighter? Not the superstar. Not the entertainer. If he were to retire right now, how would we define his athletic achievement?

Real or Not: Poirier won't regret decision, win or lose

If Poirier loses Saturday, he falls back into a pack of elite contenders at lightweight. He would likely need at least one more win to get another title shot.

If that were to happen, would he regret his choice not to fight for the belt first and then hope he could finish the lucrative trilogy against McGregor?

Could McGregor put title shot on hold if he beats Poirier?

If Dustin Poirier wins the UFC 264 main event, there's little doubt he'll challenge champion Charles Oliveira in his next fight. But what if Conor McGregor wins?

Will McGregor decide the time is finally right to revisit the Nate Diaz trilogy? He'd be playing with house money at that point, and I don't see why the UFC wouldn't get on board with it. What I mean is: Win or lose against Diaz, he could still fight for the 155-pound title next.

The charity saga: McGregor donates, but not to Poirier

Conor McGregor donated $500,000 to a Boys & Girls Club in Louisiana as an apparent resolution to an issue he had with rival Dustin Poirier.

In April, McGregor and Poirier bickered on social media about McGregor's pledge to donate $500,000 to Poirier's The Good Fight Foundation. Poirier tweeted that McGregor reneged on his promise following Poirier's TKO win over McGregor at UFC 257 on Jan. 24. McGregor shot back that his team wanted more details about what the money would be used for.

Sept. 27, 2014: The first time they fought

Conor McGregor (16-2) made quick work of another UFC featherweight, knocking out Dustin Poirier with a grazing left hand at 1:46 of the first round.

There was some controversy over whether McGregor hit Poirier (16-4) in the back of the head with his elbow as he followed through, but referee Herb Dean made no such signal, and Bob Bennett, Nevada State Athletic Commission executive director, told ESPN.com the elbow landed to a legal area of Poirier's head.

"He caught me with one, but other than that I feel good. I'll have to go watch it back, but it felt great," McGregor said.

"I'm honored to hear a percentage of the tickets were bought in Ireland and my countrymen came to support me. When one of us go to war, we all go to war. Our countrymen have been fighting our whole lives. This is where we come from."

How Poirier grew after losing to McGregor and his head games

The only time Dustin Poirier wanted to fight an opponent outside of the cage was the week of UFC 178.

Poirier remembers standing behind a curtain at the MGM Grand Conference Center in Las Vegas in September 2014, waiting to get on the scale. He recalls seeing a few scuffles in the crowd, which was packed with Irish fans. He remembers being dehydrated and anxious to weigh in. And he remembers tension after weeks of being the target of Conor McGregor's trash talk.

"I wanted to make the guy pay, you know? I was angry," Poirier says. "I remember wanting to fight him at the weigh-in, which is crazy to look back at. I was just in such a weird place in my mind."

McGregor's journey: Success, controversy, star power

UFC president Dana White remembers the first time he heard the name Conor McGregor, a name that would forever change the promotion.

White was in Dublin to receive an award from Trinity College in 2013 when he invited UFC fans on Twitter to join him at a nearby pub after the ceremony. Drinks would be covered by the UFC president.

It was that night, Feb. 11, when he first heard a name that would become the most talked about in UFC history.

"The place was packed, full of people," White said. "I was in there with the fans all night, and everybody kept talking about Conor McGregor."
