Conor McGregor is "ready and raring to go" after he and Dustin Poirier both made weight ahead of their blockbuster showdown at UFC 257.

'The Notorious' weighed in at 155lbs when he took to the scales, with Poirier a pound heavier ahead of the much-anticipated bout on Fight Island in Abu Dhabi.

McGregor defeated Poirier in a first-round knockout when the two first met at featherweight almost seven years ago but is sure to face an altogether sterner challenge this time around in a fight taking place at lightweight.

"I'm in fight mode now. That's for sure. The weight is down. We're closing in," McGregor said.

"It's f****** fight time now and I'm ready and raring to go. I cannot wait to get into this arena, this Octagon.

"I've been highly impressed, I think the whole business has been highly impressed, after that loss many, many years ago, he rose up became champion and has given so much back.

"I am honoured to share the Octagon with this man. I know we have this competitive fire, and it's still there, there's no denying that and it's going to be a good fireworks filled bout but the respect is admirable for this man from me.

"Everyone, I'm so excited to be back."

There was no love lost between the two men when the pair fought in 2014 but the histrionics have been replaced by a much more amicable and respectable tone this time around.

At the weigh-in, Poirier provided McGregor with a bottle of his hot sauce and praised the Irishman and his team for reaching out to his foundation, but insists he is prepared for battle.

"I don't want to seem like we are up here giving each other back massages but I just wanted to clear the air," Poirier said.

"Conor's team, McGregor Sports Entertainment did reach out to my foundation and they are starting the donation to the good fight foundation and we have huge plans for that.

"So Conor, man to man, you are going to help a lot of people with that.

"My whole career has aligned me for tomorrow night, and I'm here to be victorious and get my hand raised by any means necessary.

"I'm leaving it all out there. Let's go."

Andy Murray has withdrawn from the Australian Open a little over a week after testing positive for coronavirus.

Murray, a five-time finalist in Melbourne, went into isolation at home after returning a positive test on January 14.

The three-time major winner, ranked 123rd in the world, had hoped to compete at the first grand slam of the year after being granted a wildcard.

However, tournament organisers indicated it would be difficult for Murray to remain in the draw as he would be unable to travel via one of the official charter flights containing other players before going through the required period of quarantine.

On Friday, the 33-year-old confirmed he had been unable to come to a "workable" solution with authorities.

In a statement carried by The Guardian and other UK media outlets, Murray said: "Gutted to share that I won't be flying out to Australia to compete at the Australian Open.

"We've been in constant dialogue with Tennis Australia to try and find a solution but we couldn't make it work.

"I want to thank everyone there for their efforts, I'm devastated not to be playing out in Australia. It's a country and tournament that I love."

The build-up to this year's Australian Open has been impacted by players having to spend a two-week quarantine in their hotel accommodation.

A total of 72 competitors have been unable to leave their rooms after positive coronavirus tests among passengers on the chartered flights to Melbourne.

Players have been unable to access practice courts and many have complained on social media about sub-standard food and conditions, with Yulia Putintseva, the world number 28, sharing videos showing mice in her room.

The tournament is due to start on February 8.

Jenson Button has returned to Williams in a senior advisory role after agreeing a multi-year deal.

Button was given his Formula One break by Williams 21 years ago when he was handed a drive for the 2000 season.

The 41-year-old Briton went on to be crowned F1 world champion during his time with Brawn in 2009 and retired in 2016 with 15 race victories to his name.

Button now returns to Williams, who were sold to American private investment firm Dorilton Capital last year as the Williams family ended their 43-year-old involvement in F1.

He will be tasked with passing on his experience at grands prix, while also attending team events in the United Kingdom.

Englishman Button said: "I am so delighted to once again be able to say that I've signed for Williams. Back when I was 19 it was a moment that changed my life and, despite the fact it was over 20 years ago, I already feel like I never really left.

"Sir Frank Williams showed faith in me which I will be eternally grateful for and I am incredibly excited to have the chance to come back and help the team as it strives once more for success."

Incoming Williams Racing chief executive Jost Capito said: "Bringing Jenson back on board is another positive step to help us move forward as a team both on and off track. Jenson has always been a friend of the team and so it is great to welcome him back into the Williams family.

"Back in 2000, Sir Frank saw the promising talent Jenson had as a driver and gave him his first opportunity in F1. He more than fulfilled that initial promise throughout a glittering career that culminated in world championship glory.

"More recently, he has shown his acumen in both the business and broadcasting worlds and remains a widely respected figure in the paddock."

Conor McGregor has promised to put on an emphatic show against Dustin Poirier on Fight Island this weekend.

You don't get the nickname "Mystic Mac" for nothing and his latest bout, albeit it occurred 12 months ago, was a rapid dismantling of Donald Cerrone so it would not be a surprise to see the Irishman be true to his word.

Poirier is one of the most respected fighters in UFC, though, and if McGregor takes his eye off the prize then an upset could be on the cards.

The beauty of MMA is no one really knows how a fight will pan out but, that being said, we've tried to answer some of the big questions ahead of a blockbuster UFC 257 in Abu Dhabi.

Wait, didn't Conor McGregor retire?

Well…he said he had. Here's the thing, McGregor has twice before said he's retired and both times come back to fight. The pandemic seemed to derail McGregor's rejuvenated focus but no one truly believed he was done for good.

Okay, so tell me who is Dustin Poirier?

Seasoned UFC fans need no introduction to Poirier, an experienced campaigner with an excellent MMA CV. Eddie Alvarez, Justin Gaethje, Anthony Pettis and Max Holloway are just some of the elite names Poirier has beaten. The latter fight earned him the interim lightweight belt but he came up short when fighting the fearsome Khabib Nurmagomedov for the full title. Poirier rebounded to defeat Dan Hooker in June and now he gets another crack at McGregor.

Oh, they've fought before…what happened the first time around?

McGregor scored a huge first-round knockout victory that really catapulted him to new levels of stardom and it goes without saying the 32-year-old has since transcended the world of UFC and is one of the most globally recognised sports stars.

What's different this time?

Well firstly, both men are older. Their first bout occurred in April 2014 and there was no love lost in a typically robust build-up to a McGregor fight. But the histrionics have largely been replaced by the more respectful tones of experienced fighters – both of whom are now fathers. Poirier has lost just twice since his defeat to McGregor, while this bout takes place at lightweight, whereas their first encounter was at featherweight.

Where will the fight be won?

Poirier is a completely different animal this time around – the emotive blow-for-blow scrapper has been replaced by a colder, more calculated tactician in the Octagon. McGregor remains a lethal striker and both men will want to dominate standing up. If McGregor is on song it's hard to look past a win for the Irishman.

Will the winner get to fight Khabib?

Well it's certainly the one McGregor is hankering for. Their first bout of course ended in an ugly brawl between the two camps, but McGregor remains desperate to prove he can avenge that submission defeat from October 2018. Poirier is also on a five-man shortlist of fighters to face Khabib, who for now remains retired following his win over Gaethje late last year. The unbeaten Russian met with UFC president Dana White to discuss the possibility of a comeback but it is by no means certain he returns.

'Mystic Mac' is back!... and not for the first time.

Conor McGregor steps back into the Octagon having not fought since knocking out Donald Cerrone after just 40 seconds at UFC 246 over 12 months ago.

That was supposed to be the first of three fights in 2020 for a rejuvenated McGregor, who had spent 14 months away following the ugly melee that followed his loss to Khabib Nurmagomedov in October 2018.

Then, of course, a global pandemic caused chaos to the world of sport and, in June, McGregor announced he was retiring from fighting, citing he was just not excited about the MMA game.

Fans of McGregor and the UFC had been here twice before and the scepticism that met his announcement was justified when it was confirmed the big-talking Irishman would face off against Dustin Poirier for the second time in his career.

Ahead of that bout on Fight Island in Abu Dhabi this weekend for UFC 257, we take a look back at McGregor's past 'comeback' scraps.

August 20, 2016 – McGregor beats Diaz by majority decision

In March of the same year, McGregor suffered his first loss fighting in the UFC after submitting to a rear-naked choke from Nate Diaz at UFC 196.

McGregor was slated to have his rematch against Diaz at UFC 200 but in April posted on Twitter: "I have decided to retire young. Thanks for the cheese."

Two days later, he clarified that he had not actually retired but had fallen out with UFC bosses over promotional work and the fight was pulled.

But the bout was eventually staged at UFC 202 in an absolute classic that saw McGregor avenge the defeat via majority decision.

McGregor floored his opponent in round one and Diaz was downed twice more in the second round, but the Irishman survived a series of brutal blows in the third.

Diaz scored a takedown late in the fifth but McGregor saw out the time with the three judges scoring it 48-47, 47-47, 48-47, leading to a famous declaration: "The king is back!"

January 18, 2020 – McGregor beats Cerrone by knockout

Five months on from the ugly aftermath of the Khabib defeat, McGregor announced, "I've decided to retire from the sport formally known as 'Mixed Martial Art'."

High-profile incidents away from the Octagon had plagued McGregor, while he also launched his 'Proper No. Twelve' whiskey brand.

Still, the lure of the UFC proved too much for one of the all-time greats and a focused McGregor was back to fight Cerrone in Las Vegas in a bout pitting two of the sport's most popular stars against one another.

McGregor put on an absolute clinic and a series of brutal blows led to the bout being waved off after just 40 seconds. It marked his first victory in the Octagon since November 2016 when he defeated Eddie Alvarez to win the UFC lightweight title and become the company's first ever dual champion.

After the fight, McGregor said: "I made history tonight. I set a new record. I'm the first fighter in UFC history to secure knockout victories at featherweight, at lightweight and now at welterweight - across three weight divisions, so I'm very proud of that."

January 23, 2021 – McGregor v Poirier?

"Hey guys I've decided to retire from fighting. Thank you all for the amazing memories! What a ride it's been!"

And with that McGregor was done... again.

But really we knew he wasn't, and once more McGregor will step into the Octagon against an opponent he is familiar with.

Almost seven years have passed since McGregor earned 'Performance of the Night' honours after the fight was stopped after one minute and 46 seconds of the first round when 'The Notorious' put Poirier on the back foot then caught his opponent with a huge left hook behind the ear.

So the question remains: how will McGregor fare on his latest comeback from 'retirement'?

LeBron James said he was not fuelled by his MVP snub as he scored a season-high 34 points in a Los Angeles Lakers victory over Giannis Antetokounmpo's Milwaukee Bucks.

James also provided eight assists and claimed six rebounds in a 113-106 win for the NBA Western Conference leaders on Thursday.

Antetokounmpo, the NBA MVP and Defensive Player of the Year winner last season, finished with a 25-point haul but could not prevent the Bucks - third in the Eastern Conference - from slipping to 9-6.

Superstar James dismissed a suggestion he may have been out to prove a point after missing out on the MVP award last year, as the Lakers extended their franchise away record to eight consecutive wins on the road to start the season.

He told reporters: "I think you know me. I think all of you guys know me. It's never been about individual.

"It's all about the team success and that's all that matters. I can care less about that. I just try to play well and help our team win versus any opponent and that’s what it’s all about."

Lakers star Anthony Davis declared "I suck right now" after he scored 18 points, took nine rebounds, laid on six assists and came up with two blocks.

Yet James says his fellow All-Star is being too hard on himself.

"He's continuing to grow every single game. Every single film session, we kind of break those things down - what he sees on the floor," James said.

"Tonight was another example of him just seeing the other side of the floor and putting the ball on time, on target and guys knocking it down."

Los Angeles Lakers star Anthony Davis provided a scathing assessment of his form despite another road win for the NBA champions, saying "I suck right now".

The Lakers extended their franchise away record to eight consecutive wins on the road to start the season by topping the Milwaukee Bucks 113-106 on Thursday.

LeBron James posted a season-high 34 points, while All-Star team-mate Davis had 18 points, nine rebounds, six assists and two blocks for the Western Conference-leading Lakers (12-4).

Davis, though, was far from pleased with his performance after shooting just eight-of-18 from the field and missing his only three-point attempt.

"Right now, to be hard on myself, man, I think I suck right now," Davis said post-game.

"I'm not making shots, I'm not making free throws. But I think tonight my aggressiveness, just being a poster and getting to the paint allowed guys to get open."

David added: "My aggressiveness tonight. That's the only way I feel like I'm gonna get out of this funk or whatever that I'm in.

"I put a lot of pressure on myself to be a better basketball player every game, and that's what I'm gonna continue to do."

"I trust my team-mates. AC [Alex Caruso] hit one for me. Bron hit one and Kenny [Kentavious Caldwell-Pope] hit one, and they're in the right spots where I want guys when I have the ball in the post," Davis continued.

"And just [am] able to make the read with their guys doubling or collapsing to the paint when I get there, and was able to kick it out and those guys made shots."

The Los Angeles Lakers stayed perfect on the road after beating the Milwaukee Bucks 113-106 in the NBA on Thursday.

LeBron James posted a season-high 34 points as defending champions the Lakers extended a franchise record after winning their eighth consecutive away game to start the season.

James also tallied eight assists and six rebounds to help the Lakers – 8-0 on the road – bounce back from a loss in the first of a seven-game road trip, upstaging reigning two-time MVP Giannis Antetokounmpo in the process.

Kentavious Caldwell-Pope had 23 points for the Western Conference-leading Lakers (12-4) in Milwaukee, where the Bucks (9-6) dropped back-to-back games.

Antetokounmpo's double-double of 25 points and 12 rebounds were not enough for the Bucks, who also had solid contributions from Jrue Holiday (22 points) and Khris Middleton (20 points).

Curry stars

Stephen Curry put up 30 points, but the Golden State Warriors still went down 119-104 at home to the New York Knicks. The two-time MVP moved into fourth place on the franchise's all-time games played list after making his 714th regular-season appearance, surpassing Paul Arizin. RJ Barrett's 28 points for the Knicks were a career high.

Golden State's Eric Paschall scored his 1,000th career point in his 74th game, reaching the 1,000-point mark in the fewest amount of games played by a Warriors second round draft pick in the Modern Draft era (since 1966). Previously, Gilbert Arenas did so in 79 games.

Donovan Mitchell's season-high 36 points fuelled the Utah Jazz's 129-118 win over the New Orleans Pelicans. Mitchell was 11-of-19 shooting from the field, while he made six of eight three-point attempts. The Jazz have won seven straight games.

Schroder struggles in Milwaukee

Dennis Schroder failed to get going for the Lakers. The offseason recruit was just two of 10 from the field, while missing all three of his attempts from beyond the arc for four points in 33 minutes.

Kelly Oubre Jr. did not perform much better for the beaten Warriors. His seven points were on two-of-11 shooting from the field at home to the Knicks. Oubre also missed all four of his three-point attempts.

Steph with the behind-the-back pass

While the Warriors were unable to claim the win, Curry produced a couple of highlight moments. His behind-the-back pass to set up Draymond Green for the three-pointer was the pick of the bunch.

Thursday's results

Los Angeles Lakers 113-106 Milwaukee Bucks
Utah Jazz 129-118 New Orleans Pelicans
New York Knicks 119-104 Golden State Warriors

Celtics at 76ers

The Boston Celtics (8-5) and Eastern Conference rivals the Philadelphia 76ers (10-5) will do battle again at Wells Fargo Center on Friday after Joel Embiid's 42-point double-double inspired Doc Rivers' team midweek.

The list of Kobe Bryant's accomplishments during his 20 NBA seasons is almost too long to recount.  

Yet among his All-Star selections, championships and signature moments, his 81-point game stands out both for its historical significance and its representation of Bryant's personality and career.  

Friday marks the 15th anniversary of this astounding feat, the closest anyone has ever come to Wilt Chamberlain's NBA scoring record, a seemingly impossible 100 points.  

Chamberlain reached triple digits on March 2, 1962, in a much different NBA than the one Bryant faced. Chamberlain averaged 50.4 points per game that season while playing every minute of every game. In scoring 100 points, he led the Philadelphia Warriors to a 169-147 win over the New York Knicks.  

Bryant's feat, while falling short of the century mark, remains the gold standard for scoring in the modern game.  

On January 22, 2006, the Toronto Raptors travelled to Los Angeles to face the Lakers and were gaining confidence. After a desperate 1-15 start, Toronto's season had stabilised, and the Raptors entered Staples Center having won 10 of their previous 16 games. But Toronto had just allowed 113 points in a win against Seattle and entered the game giving up 102.2 points per game, third-most in the NBA.  

Bryant went on to make history, making 28 of his 46 field goal attempts – including 7-for-12 shooting from beyond the arc – and hitting 18 of 20 free throws.  

Perhaps the greatest testament to Bryant's achievement is that no player over the 15 years since has come particularly close to scoring 81 points in a game, despite several factors working in their favor.  

In 2005-06, a team got 79.0 field goal attempts per game on average, the fourth-slowest pace of all time. Almost any other season in NBA history would have been more likely to have an astounding scoring outburst.  

In the 1961-62 season, when Chamberlain made history, teams averaged 107.7 shots per game and attempted 37.1 free throws per game, nearly 11 more than in 2005-06.  

The league has picked up its pace since Bryant's feat as well, with teams attempting 88.8 field goals last season, giving the modern player more opportunities than Bryant had.  

The other advantage that current players have in piling up stats is the three-point shot.  

Bryant's 7-for-13 performance from deep was dynamic in 2006. Twice in the 2005-06 season, Chicago Bulls guard Ben Gordon made nine three-pointers in a game to lead the league. Only four players made more than seven threes in a game that season. The average team attempted 16.0 threes per game.  

Teams are launching an average of 35.1 three-point attempts during this young season, on pace to be the 10th in a row with an increase in long-range shooting. Ten players have already made eight or more threes in a game this season, despite most teams having played about 15 games.  

Even with a faster pace and increased frequency of long-distance barrages in the modern game, Bryant's 81-point mark still appears virtually unobtainable.  

Since that date, Devin Booker's 70 points are the high mark. There have been 19 games in which a player scored 60 or more, four by Bryant himself.  

One integral element to Bryant's scoring explosion was the composition of that Lakers team. Bryant did have Lamar Odom, but LA's other starters on that historic night were Kwame Brown, Chris Mihm and Smush Parker. The Lakers finished that season 45-37, far from a bad team, but Bryant scored 35.4 points per game as the Lakers relied on him almost entirely for scoring.  

Bryant scored 34.7 percent of the Lakers' points that season, the fourth-highest scoring share of all time. Only Chamberlain and Michael Jordan have scored a higher percentage of a team's points in a season.  

Given that profile, there are a few players who stand out as possible candidates to make a run at a historical scoring game in the foreseeable future.  

Booker, James Harden and Kemba Walker all have at least one 60-point game in their careers but now find themselves on teams with better supporting casts, making it unlikely they could get enough shots to chase history.  

Damian Lillard, however, could fit the mould perfectly. Team-mates CJ McCollum and Jusuf Nurkic will both miss significant time due to injuries, and Lillard has crossed the 60-point barrier three times, all within the past 15 months. Add his 36.2 minutes per game – top 10 in the league – and 10.1 three-point attempts per game, and Lillard seems as likely as anyone to produce a dazzling scoring total.  

Stephen Curry scored a career-high 62 points on January 3 and will be a constant centerpiece in the Golden State Warriors' offense without Klay Thompson. While Curry is 25th in the league at 34.4 minutes per game, his historic three-point shooting makes him a constant threat.  

League scoring leader Bradley Beal remains in the mix, despite the Washington Wizards acquiring ball-hungry Russell Westbrook in the offseason. Westbrook has often taken games off due to rest, and Beal scored 60 on January 6. He also carries the advantage of getting to the free throw line 9.5 times per game, fourth in the NBA this season.  

That list ignores perennial MVP candidates Giannis Antetokounmpo, Kevin Durant and LeBron James, as well as young dynamos like Trae Young and Luka Doncic.  

The fact that there are so many candidates to make a run at 81 points without anyone coming close in the past 15 years indicates just how phenomenal Bryant's accomplishment was.  

Whether Bryant's mark lasts forever or is eventually bested, it will always be a brilliant snapshot of an all-time great player. He won championships before and after his 81-point game, but Bryant's legacy is as a scorer and a relentless competitor, perfectly represented by that gaudy scoring total 15 years ago.  

Bryant wore number eight and number 24 during his decorated career, but 81 is just as important to his legacy.

Saul 'Canelo' Alvarez will be back in the ring on February 27, defending his WBA and WBC super-middleweight titles against Avni Yildirim.  

Canelo claimed the belts in December, handing Callum Smith his first career defeat as he recorded a unanimous points triumph over the Englishman in San Antonio, Texas.  

Now the Mexican superstar will head to Florida for his next outing, the Hard Rock Stadium in Miami Gardens chosen to stage the clash with Yildirim.  

While keen to eventually unify the 168-pound division, the 30-year-old must first deal with his mandatory challenger for the WBC strap.  

"Avni Yildirim is a good boxer and I know we will put on an exciting fight," said Canelo.   

"I'm very glad that we are able to bring this event to Miami, a short distance from where my hero, Muhammad Ali, trained.   

"February 27 will be a great night for the sport."

Yildirim, who owns a 21-2 record as a pro, previously challenged for the vacant WBC belt in February 2019, losing via a technical decision after opponent Anthony Dirrell suffered a cut that forced their bout to be stopped.  

However, the 29-year-old - whose other loss came against Chris Eubank Jr in 2017 - is ready to go to war as he aims to cause a huge upset.  

"I am honoured as a mandatory to fight again for the big green belt - thank you to everyone who is involved," Yildirim said in a press release to announce the date. 

"I always give my all – and everybody should be ready to see a war. I am coming to make my country proud – I am representing the whole of Turkey."

The NBA has announced the Memphis Grizzlies' next three games have been postponed in accordance with COVID-19 protocols.

Memphis had already seen Wednesday's scheduled meeting with the Portland Trail Blazers called off, the Grizzlies not having the league-required minimum of eight players available for action.

The same teams had been due to meet on Friday, however that clash will no longer be going ahead as planned.

Back-to-back games with the Sacramento Kings, set to take place on Sunday and Monday, are also postponed due to the combination of unavailable Grizzlies players and contact tracing for others on the roster. 

"The Memphis Grizzlies' next three games - Friday, January 22 at Portland and Sunday, January 24 and Monday, January 25 vs Sacramento - have been postponed in accordance with the NBA's health and safety protocols," the NBA said in a statement.

"The games are being postponed due to unavailable players for the Grizzlies and contact tracing for other players on their roster, and in order to ensure the health and safety of players on both teams."

In total, 20 games have been postponed during the NBA regular season as the competition deals with the ongoing impact of the coronavirus pandemic.

The Grizzlies are 7-6 on the season and on a five-game winning streak. Following the postponements, they are next due to be in action on January 27, when they host the Chicago Bulls.

Tennis umpire Carlos Bernardes is "recovering well" after reportedly suffering a heart attack ahead of the Australian Open.

The veteran Brazilian, who has officiated in US Open and Wimbledon men's singles finals, was taken from his hotel to a Melbourne hospital on Wednesday after falling ill.

It was widely reported he had a heart attack, with Bernardes pictured on a stretcher while being loaded into an ambulance.

The ATP, which runs the men's tour and has been Bernardes' employer since 1990, offered an positive update on Thursday.

In a statement, the governing body said: "Following admittance to hospital [non-COVID related] on Wednesday in Melbourne, we are pleased to report that ATP umpire Carlos Bernardes is recovering well.

"Carlos passes on his gratitude for all the well wishes he's received, and we wish him all the best for a full recovery."

According to Brazilian tennis website TenisNews, Bernardes remains under observation but is expected to leave hospital on Saturday.

He was staying at The View, one of three hotels where Australian Open players and tennis officials are quarantining for two weeks after their arrival in the country.

Conor McGregor is still hopeful Khabib Nurmagomedov can be tempted back to the Octagon but says he should be stripped of the UFC lightweight title if he refuses to return.

Nurmagomedov called time on his career after defeating Justin Gaethje at UFC 254 in October but is in Abu Dhabi to attend the lightweight fight between McGregor and Dustin Poirier on Saturday.

Dana White met with the Russian, who he said was looking for "something spectacular" if he was to go back on his decision to hang up his gloves.

However, Nurmagomedov subsequently said fighting was not in his plans as he did not want to disappoint his mother, to whom he promised Gaethje would be his last opponent due to the death of his father and coach Abdulmanap.

Asked about those remarks at a news conference to preview UFC 257, White responded: "I've told you guys. We'll see what happens this week."

McGregor, who was submitted by Nurmagomedov at UFC 229 in a fight that was overshadowed by a post-bout melee outside the Octagon, added "we'll get him", before claiming that the lightweight title will soon be up for grabs.

"I'd make the case if that man [Nurmagomedov] is continuing to dodge this and dodge the commitment of competing again, the title should be stripped and we should be engaging in a title fight," said McGregor.

"I'm sure it'll happen after this bout. I'm interested to hear what the excuses are … but I predict a title strip.

"As long as we fight again there'll be no issue [between us], that's it. If he continues to run, I'm not sure. We'll see what happens.

"The world knows this fight is not over, this war is not over. The sport needs it to happen. I'm not gonna chase it if he doesn't want it and I'll keep my calm and move on."

The fight with Poirier will be just McGregor's third at lightweight, having returned from a second retirement at welterweight when he took on Donald Cerrone in January last year.

The former featherweight and lightweight champion claimed to have retired again, finding it difficult to fulfil his three-fight plan for 2020 due to the coronavirus pandemic, but he is now anticipating a long run at 155 pounds.

"I have not had that many fights at 155 in the UFC and I'm eager to put in a stint, to get a run going like I did with the featherweights," said McGregor.

"I think I went seven or eight fights within a year and a half. That's what I'm looking for here if they can match me up. This is the best I've ever been for sure, and I'm at 155 pounds. But if I go back to 170 you best believe that'll be the best I've ever felt also."

Poirier's camp suggested McGregor's weakness is his conditioning, but the Irishman does not agree with that assessment.

"I think it's a myth. Obviously the first [Nate] Diaz fight I went from featherweight and a month or so later I was at welterweight, that's obviously gonna have an impact and then there were other issues," he said.

"Overall, I think it's a myth. It's a myth that's out there and I hope we can answer it. I will answer it in time at some stage. I keep showing up here, someone's gonna be able to stay in there and fight with me. I hope it's this Saturday night. Do I think so? I do not. I'm in some shape here and I'm coming to put on a masterpiece."

McGregor added: "I have a million shots. I have so many weapons in my arsenal and they're all fine-tuned at this time. I'm in a phenomenal place and I look forward to going out and showcasing, painting a beautiful picture."
