In 2015, at UFC 194, he defeated Jos?? Aldo to the UFC Featherweight Championship via knockout 13 minutes to the first round, that’s the quickest victory in UFC title fight history. Upon defeating Eddie Alvarez for the UFC Lightweight Championship in UFC 205, McGregor became the first fighter in UFC history to hold titles in two weight divisions simultaneously.
McGregor began his professional boxing career in 2017. In his introduction boxing game, he was conquered by Floyd Mayweather Jr.He is the largest pay-per-view (PPV) draw MMA history, with headlined five out of those six highest-selling UFC pay-per-view events. His headline bout with Khabib Nurmagomedov in UFC 229 drew 2.4 million PPV buys, the most ever for an MMA event. His boxing game with Mayweather drew 4.3 million PPV purchases in North America, the next most in history.On 9 March 2008, McGregor had his first professional MMA bout, as a lightweight, beating Gary Morris with a second-round TKO. Following McGregor won his next battle against Mo Taylor, he made his featherweight introduction in a reduction via submission against Artemij Sitenkov. Following a victory at featherweight in his next bout against Stephen Bailey, McGregor considered a different career path before his mum contacted his trainer John Kavanagh and reinvigorated him to continue pursuing mixed martial arts. 
McGregor then won his second fight, too at featherweight, against Connor Dillon, before going back to lightweight to get a struggle against Joseph Duffy, where he obtained his next professional loss after submitting to an arm-triangle choke. After this, throughout 2011 and 2012, McGregor went on an eight-fight winning streak, during 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. Back in February 2013, UFC president Dana White chose to Dublin, Ireland to Be Given a Gold Medal of Honorary Patronage in Trinity College and was inundated with requests to signal McGregor into the UFC. After a meeting 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) declared that they had signed McGregor to some multi-fight contract.  In joining, McGregor became only the second fighter out of Ireland to compete to the company, after fellow SBG team member Tom Egan.
On April 2013, McGregor made his UFC debut against Marcus Brimage about the preliminary card of UFC on Fuel TV: Mousasi vs. Latifi.  Brimage began the battle aggressively, meeting McGregor in the center 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 a snap kick directed in his chest and torso, McGregor started to employ a looping left hand uppercut, throwing each single time Brimage would proceed forward into striking range. These uppercuts grounded Brimage soon after McGregor started to use them. The bout was stopped 1:07 into the first round.  The win also earned McGregor his first“Knockout of the Night“ award. 
McGregor was anticipated to face Andy Ogle on 17 August 2013 at UFC Fight Night 26, but Ogle pulled out of the bout citing an accident and was replaced by Max Holloway.  McGregor bewildered Holloway with his unusual boxing strategy, and his incorporation of a wide array of taekwondo kicks, many of which are not used in MMA to some substantial degree. McGregor managed to restrain the striking range by using long, non-committal low side kicks to Holloway’s knee and knee, and initiate combinations by leaping in with switch and bicycle kicks. When the fight was brought into the floor, McGregor maintained high control, performing various positional improvements, and mitigating his opponent’s offence on the ground.  McGregor won the fight by unanimous decision (30–27, 30–27, and 30–26). After the bout with Holloway, an MRI scan revealed that McGregor had torn his anterior cruciate ligament (ACL) during the bout and would require surgery, keeping him out of action for up to ten months. 
Return after injury McGregor was anticipated to confront Cole Miller on 19 July 2014 at UFC Fight Night 46 within his comeback bout after recovering from his ACL injury.  However, Miller pulled from the bout citing a thumb injury and was replaced by Diego Brand??o.  McGregor battled Brand??o in front of a loud, rowdy crowd of 9,500 at The O2 in his hometown of Dublin, Ireland. McGregor started the fight with a touch turning side kick, before finding his range and landing various taekwondo kicks, and left counters. Brand??o, a Brazilian Jiu-Jitsu black belt, attempted to instigate two takedowns, so that he could take advantage of his grappling pedigree, but both efforts were averted by McGregor. Nonetheless, a lot of the struggle was spent on the ground, as McGregor attained a takedown 1:20 to the bout. When the battle returned to the feet in the next minute, McGregor started to employ his left hand cross, and started to cut off the cage. Brand??o, trapped between the octagon and McGregor, dropped to his side after being hit by another left hand crossover as the fight went to its fourth minute.  The fight was officially halted by Faith Leon Roberts at 4:05 of the first round. The win earned McGregor his first“Performance of the Night“ award. 
Prior to his next bout, McGregor met with Lorenzo Fertitta and signed a new multi-fight contract with the UFC. McGregor next confronted Dustin Poirier on 27 September 2014 at UFC 178.  The bout was one of the most anticipated fights on the UFC 178 card, together with McGregor and Poirier two of just four men involved in the pre-fight media conference, together with the originally scheduled headliners Jon Jones and Daniel Cormier.  Part of the anticipation stemmed in the challenge that the match-up posed: 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 in the first round, by pressuring Poirier on his back foot, before exploding with a left hook behind Poirier’s ear, forcing referee Herb Dean to measure in. The end officially came at 1:46 into the first round.  This marked Poirier’s initial UFC reduction via KO/TKO, and got McGregor his second straight“Performance of the Night“ award.  From the post-fight interview with commentator Joe Rogan, McGregor cited the UFC Featherweight Championship as his second target in the organisation, stating that“If [the UFC] want, I will eliminate Chad Mendes and step into and give the fans exactly what they need; Aldo vs. McGregor.“
