Ultimate Fighting Championship (2013–gift )
UFC introduction In February 2013, the Ultimate Fighting Championship (UFC) announced that they had signed McGregor into some multi-fight contract.  In linking, McGregor became only the second fighter out of Ireland to compete to the firm, after fellow SBG team member Tom Egan.
On 6 April 2013, McGregor made his UFC debut against Marcus Brimage about the first card card of UFC on Fuel TV: Mousasi vs. Latifi.  Brimage began the fight aggressively, meeting McGregor at the center of the octagon before starting 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 started to apply a looping left hand uppercut, throwing every time Brimage would proceed forwards 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 initial”Knockout of the Night” award. 
McGregor was expected to face Andy Ogle on 17 August 2013 in 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 technique, and his incorporation of a huge variety of taekwondo kicks, many of which are not utilized in MMA to a substantial level. McGregor was able to control the striking range by using extended, non-committal low side kicks to Holloway’s knee and shin, and commence combinations by leaping in with switch and bicycle kicks. When the fight was brought into the floor, McGregor maintained top hands, performing various positional advances, and mitigating his competitor’s exemptions on the ground.  McGregor won the fight by unanimous decision (30–27, 30–27, and 30–26). After the bout with Holloway, an MRI study revealed 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 months. 
Return after injury McGregor was anticipated 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  But, Miller pulled from the bout citing a thumb injury and has been replaced by Diego Brand??o.  McGregor fought Brand??o facing a loud, rowdy crowd of 9,500 at The O2 in his hometown of Dublin, Ireland.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 touch spinning side kick, before finding his range and landing various taekwondo kicks, and left counters. Brand??o, a Brazilian Jiu-Jitsu black buckle, tried to instigate two takedowns, so he could make use of his grappling pedigree, but both attempts were avoided by McGregor. Nonetheless, much of the fight was spent on the ground, as McGregor attained a takedown 1:20 into the bout. When the battle returned to the toes in the third minute, McGregor started to use his left hand cross, and started to cut off the cage. Brand??o, trapped between the octagon and McGregor, fell to his side after being hit with the other left hand cross as the struggle went to its fourth minute.  The battle was officially halted by referee 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 fresh multi-fight contract with the UFC. McGregor next confronted Dustin Poirier on 27 September 2014 in UFC 178.  The bout was among the most anticipated fights on the UFC 178 card, with McGregor and Poirier just two of just four men involved in the pre-fight media conference, alongside the initially scheduled headliners Jon Jones and Daniel Cormier.  Part of this anticipation stemmed from the challenge that 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 in the first round, by pushing Poirier on his rear foot, before bursting with a left hook behind Poirier’s ear, forcing referee Herb Dean to step in. The finish officially came at 1:46 into the first round.  This marked Poirier’s initial UFC loss via KO/TKO, and got McGregor his second straight”Performance of the Night” award.  In the post-fight interview with commentator Joe Rogan, McGregor cited the UFC Featherweight Championship as his second target from the organisation, saying that”If [the UFC] want, I will eliminate Chad Mendes and step in and give the fans exactly what they need; Aldo vs. McGregor.”
