Conor Anthony McGregor (Irish: Conch??r Ant??in Mac Gr??ag??ir; born 14 July 1988) is an Irish professional mixed martial artist and boxer. 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 in 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 names concurrently before vacating them to sign together with the UFC. In 2015, at UFC 194, he conquered Jos?? Aldo for the UFC Featherweight Championship via knockout 13 minutes to the first round, that’s the quickest success in UFC title history. Upon beating Eddie Alvarez for the UFC Lightweight Championship at UFC 205, McGregor became the first fighter in UFC history to maintain titles in two weight divisions simultaneously.
McGregor began his professional boxing career in 2017. In his debut boxing match, he was conquered 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 events. His headline bout with Khabib Nurmagomedov at UFC 229 attracted 2.4 million PPV buys, the most ever for an MMA event. His boxing match with Mayweather drew 4.3 million PPV purchases in North America, the second most in history.On 9 March 2008, McGregor had his first professional MMA bout, as a lightweight, defeating Gary Morris using a second-round TKO. After McGregor won his second battle against Mo Taylor, he made his featherweight introduction in a loss via entry against Artemij Sitenkov. Following a success at featherweight in his next bout against Stephen Bailey, McGregor contemplated a different career path before his mother contacted his coach John Kavanagh and reinvigorated him to keep on pursuing combined martial arts. 
McGregor then won his second battle, also at featherweight, against Connor Dillon, before moving back to lightweight for a struggle against Joseph Duffy, where he received his next expert reduction 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 made a trip to Dublin, Ireland to receive a Gold Medal of Honorary Patronage in Trinity College and has been inundated with requests to sign McGregor into the UFC. Following a meeting with McGregor, and speaking with UFC CEO Lorenzo Fertitta, White offered him a contract days later.
Ultimate Fighting Championship (2013–present)
UFC debut In February 2013, the Ultimate Fighting Championship (UFC) declared that they had signed McGregor into some multi-fight contract.  In joining, McGregor became only the second fighter from Ireland to compete to the company, following fellow SBG team member Tom Egan.
On 6 April 2013, McGregor made his UFC debut against Marcus Brimage on the first card 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 susceptible to some snap kick directed at his chest and chin, McGregor began to employ a looping left hand uppercut, throwing every time Brimage would proceed forwards into striking variety. These uppercuts grounded Brimage soon after McGregor began to use them. The bout was stopped 1:07 into the first round.  The win also earned McGregor his initial”Knockout of the Night” award. 
McGregor was anticipated to confront Andy Ogle on 17 August 2013 in UFC Fight Night 26, but Ogle pulled out of this bout citing an accident and was replaced by Max Holloway.  McGregor bewildered Holloway together with his unusual boxing technique, and his incorporation of a wide array of taekwondo kicks, many of which aren’t utilized in MMA to a substantial degree. McGregor managed to restrain the striking range by using long, non-committal low side kicks to Holloway’s knee and shin, and commence mixes by jumping with bike and switch kicks. After the battle was brought into the ground, McGregor maintained high control, performing various positional improvements, and mitigating his competitor’s exemptions on the floor.  McGregor won the fight by unanimous decision (30–27, 30–27, and 30–26). Following the bout with Holloway, an MRI study showed that McGregor had torn his anterior cruciate ligament (ACL) during the bout and would require operation, keeping him out of action for up to ten weeks. 
Return after injury McGregor was expected to confront Cole Miller on 19 July 2014 in UFC Fight Night 46 in his comeback bout after recovering from his ACL injury.  However, 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 in The O2 in his hometown of Dublin, Ireland. McGregor began the struggle with a touch spinning 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 he could make use of his grappling pedigree, but both efforts were averted by McGregor. Nonetheless, a lot of the struggle was spent on ground, as McGregor attained a takedown 1:20 into the bout. When the fight returned to the toes in the third minute, McGregor began to employ his left hand crossover, 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 second.  The battle was officially halted by referee Leon Roberts at 4:05 of the very first round. The win earned McGregor his initial”Performance of the Night” award. 
Prior to his next bout, McGregor met with Lorenzo Fertitta and signed up 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, with McGregor and Poirier just two of just four men involved with the pre-fight press conference, alongside the initially scheduled headliners Jon Jones and Daniel Cormier.  Part of this anticipation stemmed in the challenge that the match-up posed: Poirier was McGregor’s first opponent ranked in the UFC’s top ten featherweights.  Despite McGregor landing 9 significant strikes to Poirier’s 10, he managed to secure a victory early on in the first round, by pushing Poirier onto his back foot, before exploding with a left hook supporting Poirier’s ear, forcing referee Herb Dean to step in. The finish officially came at 1:46 to the first round.  This marked Poirier’s first UFC loss 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 next target in the organisation, stating that”If [the UFC] desire, I will remove Chad Mendes and step in and give the fans exactly what they want; Aldo vs. McGregor.”
