He’s the former Ultimate Fighting Championship (UFC) featherweight and lightweight winner. As of 1 July 2019, he is ranked #3 in the official UFC lightweight rankings and #9 from the official UFC pound-for-pound ranks.
McGregor started his MMA career in 2008 and, in 2012, he won both the Cage Warriors Featherweight and Lightweight Championships, holding both titles simultaneously before vacating them to sign with the UFC. In 2015, at UFC 194, he conquered Jos?? Aldo for the UFC Featherweight Championship via knockout 13 seconds into the first round, which is the fastest victory in UFC title history. Upon defeating Eddie Alvarez for the UFC Lightweight Championship at UFC 205, McGregor became the first fighter in UFC history to hold titles in two weight divisions simultaneously.
McGregor started his professional boxing career in 2017. In his debut boxing game, he was defeated by Floyd Mayweather Jr.He is the largest pay-per-view (PPV) draw in MMA history, with headlined five from the six highest-selling UFC pay-per-view occasions. His headline bout with Khabib Nurmagomedov at UFC 229 drew 2.4 million PPV purchases, the most ever for an MMA event. His boxing match with Mayweather attracted 4.3 million PPV purchases in North America, the next most from history.On 9 March 2008, McGregor had his first professional MMA bout, as a lightweight, defeating Gary Morris with a second-round TKO. After McGregor won his second fight against Mo Taylor, he made his featherweight debut in a loss via submission against Artemij Sitenkov. Following a victory at featherweight in his next bout against Stephen Bailey, McGregor contemplated another career path before his mother contacted his trainer John Kavanagh and reinvigorated him to continue pursuing combined martial arts. 
McGregor then won his second fight, also at featherweight, against Connor Dillon, before moving back to lightweight for a struggle against Joseph Duffy, where he received his second professional reduction after submitting to an arm-triangle choke. Following this, during 2011 and 2012, McGregor went to an eight-fight winning streak, through which he won both the CWFC Featherweight and Lightweight championships, making him the first European professional mixed martial artist to carry names in two branches simultaneously. In February 2013, UFC president Dana White made a trip to Dublin, Ireland to Be Given a Gold Medal of Honorary Patronage from Trinity College and was inundated with requests to sign McGregor into the UFC. After a meeting with McGregor, and speaking with UFC CEO Lorenzo Fertitta, White offered him a contract later.
Ultimate Fighting Championship (2013–gift )
UFC introduction In February 2013, the Ultimate Fighting Championship (UFC) announced that they had signed McGregor to some multi-fight contract.  In joining, McGregor became only the second fighter from Ireland to compete for the company, following fellow SBG team member Tom Egan.
On 6 April 2013, McGregor made his UFC debut against Marcus Brimage about the preliminary card of UFC on Fuel TV: Mousasi vs. Latifi.  Brimage started the fight aggressively, meeting McGregor at the middle of the octagon before launching a flurry of strikes to push him . McGregor, repeatedly throwing a counter left hand, seen little success with his first striking. After discovering that Brimage was vulnerable to some snap kick directed in his chest and torso, McGregor began to employ a looping left hand uppercut, throwing each time Brimage would proceed forwards into striking range. These uppercuts grounded Brimage shortly after McGregor began to use them. The bout was stopped 1:07 to the first round.  The win also earned McGregor his first”Knockout of the Night” award. 
McGregor was anticipated to confront Andy Ogle on 17 August 2013 at UFC Fight Night 26, but Ogle pulled out of this bout citing an injury and was replaced by Max Holloway.  McGregor bewildered Holloway together with his unusual boxing strategy, and his incorporation of a huge array of taekwondo kicks, many of which aren’t used in MMA to some substantial degree. McGregor was able to restrain the striking range using extended, non-committal low side kicks to Holloway’s knee and knee, and commence combinations by jumping with bike and switch kicks. When the battle was brought into the ground, McGregor maintained high control, performing various positional improvements, and mitigating his competitor’s exemptions on the ground.  McGregor won the fight by unanimous decision (30–27, 30–27, and 30–26). Following the bout with Holloway, an MRI scan showed that McGregor had torn his anterior cruciate ligament (ACL) throughout the bout and might require operation, keeping him out of action for up to ten months. 
Return after trauma McGregor was expected to confront Cole Miller on 19 July 2014 at UFC Fight Night 46 in his comeback bout after recovering from his ACL injury.  But, Miller pulled out of this bout citing a thumb injury and has been replaced by Diego Brand??o.  McGregor battled Brand??o facing a loud, rowdy crowd of 9,500 at The O2 in his hometown of Dublin, Ireland. McGregor began the struggle with a signature spinning side kick, before finding his range and landing various taekwondo kicks, and left counters. Brand??o, a Brazilian Jiu-Jitsu black buckle, attempted to instigate two takedowns, so he could take advantage of his grappling pedigree, but both attempts were avoided by McGregor. Nonetheless, much of the struggle was spent on the ground, as McGregor achieved a takedown 1:20 into the bout. After the fight returned to the feet in the next minute, McGregor started to use his left hand cross, and began to cut off the cage. Brand??o, trapped between the octagon and McGregor, dropped to his side after being hit with another left hand crossover as the fight went to its fourth minute.  The fight was officially halted by referee Leon Roberts at 4:05 of the very first round. The triumph earned McGregor his initial”Performance of the Night” award. 
Before his next bout, McGregor met with Lorenzo Fertitta and signed a new multi-fight contract with the UFC. McGregor next faced Dustin Poirier on 27 September 2014 at UFC 178.  The bout was one of the most anticipated fights on the UFC 178 card, with McGregor and Poirier just two of just four men involved with the pre-fight media conference, alongside the initially scheduled headliners Jon Jones and Daniel Cormier.  Part of this expectancy stemmed from the challenge the match-up introduced: Poirier was McGregor’s first competitor ranked in the UFC’s top ten featherweights.  Despite McGregor landing 9 significant strikes to Poirier’s 10, he was able to secure a success early on in the first round, by pressuring Poirier onto his back foot, before exploding with a left hook behind Poirier’s ear, forcing referee Herb Dean to step in. The end officially came at 1:46 into the first round.  This marked Poirier’s initial UFC reduction via KO/TKO, also got McGregor his second straight”Performance of the Night” award.  From the post-fight interview with commentator Joe Rogan, McGregor mentioned the UFC Featherweight Championship as his second goal from the organisation, saying that”If [the UFC] desire, I’ll remove Chad Mendes and step into and give the fans what they need; Aldo vs. McGregor.”
