Conor McGregor Bio, Age, Height, Wife Dee Devlin, Children, UFC 329 Comeback Injury, Net Worth & 2026 Facts

Conor McGregor is the Irish former two-division UFC champion who became the biggest draw in mixed martial arts history — and one of the richest athletes on the planet. After a five-year absence, McGregor returned at UFC 329 in July 2026, but his comeback against Max Holloway ended after just 69 seconds when he tore his right ACL. At 38, with one fight left on his UFC contract and a net worth estimated at $200 million, McGregor remains one of the most talked-about fighters in the world — trending again in October 2026 after Joe Rogan publicly questioned his motivation and Jorge Masvidal reignited their long-running feud.

Quick Facts

In the pantheon of combat-sports megastars, Conor McGregor stands alongside names like Floyd Mayweather Jr., Mike Tyson and Ronda Rousey — fighters who transcended their sports and became global brands. His rival Khabib Nurmagomedov remains the only man to beat him via submission in a major UFC title fight, while Max Holloway, who handed him his most recent loss, has emerged as the featherweight great of the post-McGregor era. And in October 2026, Jorge Masvidal added his name to the long list of fighters calling McGregor out.

Early Life & Education

Conor Anthony McGregor was born on July 14, 1988, in Crumlin, a working-class neighborhood in south Dublin, Ireland. His father, Tony McGregor, was a former semi-professional footballer, and his mother, Margaret, worked as a hotel staff member. Conor grew up with two sisters, Erin and Aoife, in a tight-knit household where money was never plentiful. He attended Coláiste Chulaann, a Catholic secondary school in Tallaght, but left at age 16 to focus on boxing — a decision that horrified his parents at the time.

McGregor’s first combat-sport love was boxing. As a teenager he trained at the Crumlin Boxing Club under coach Phil Sutcliffe, compiling an impressive amateur record and winning the Dublin Intermediate Championship. But at 17 he walked into a mixed-martial-arts gym — Straight Blast Gym Ireland (SBG) — and never looked back. Under the guidance of coach John Kavanagh, the first Irishman to earn a black belt in Brazilian jiu-jitsu, McGregor developed the striking-heavy, precision style that would make him famous. To support his fighting dream, he worked as a plumber’s apprentice and lived on welfare payments — a rags-to-riches origin story he has told countless times.

Career Journey

Irish MMA and Cage Warriors (2008–2013)

McGregor turned professional in 2008, fighting out of SBG Ireland under John Kavanagh. He quickly racked up wins on the Irish and European circuit, and by 2012 he had captured the Cage Warriors Fighting Championship featherweight and lightweight titles — holding two belts simultaneously in a major promotion, a preview of what he would do on the world stage. His brash personality, sharp suits and unshakable self-belief made him must-see TV even before the UFC came calling.

UFC Rise: The Mystic Mac Era (2013–2016)

McGregor debuted in the UFC on April 6, 2013, knocking out Marcus Brimage in 67 seconds. Six fights later he was the biggest star the sport had ever seen. His run included:

• UFC 178 (Sept 2014): Knocked out Dustin Poirier in 106 seconds at featherweight
• UFC 189 (July 2015): Stopped Chad Mendes with a second-round TKO to win the interim featherweight title
• UFC 194 (Dec 2015): Knocked out Jose Aldo in 13 seconds — the fastest title-fight finish in UFC history — to claim the undisputed featherweight championship
• UFC 205 (Nov 2016): Stopped Eddie Alvarez in the second round to become the first simultaneous two-division champion in UFC history, holding both the featherweight and lightweight belts at once

Mayweather, Khabib and the $100M Boxing Match (2017–2018)

In August 2017, McGregor crossed into boxing to face undefeated legend Floyd Mayweather Jr. in a spectacle that generated 4.3 million pay-per-view buys. McGregor lasted 10 rounds — further than many expected — before losing by TKO. He earned approximately $100 million from the bout, the single biggest payday of his career. Three months later, in October 2018, he returned to the UFC to challenge Khabib Nurmagomedov for the lightweight title at UFC 229. The fight was marred by a post-bout brawl, and Khabib submitted McGregor in the fourth round. Despite the loss, McGregor earned an estimated $50 million from the event — and the footage of the chaos became the most-watched moment in UFC history.

Broken Leg and the Long Absence (2021–2026)

McGregor’s last UFC win came on January 18, 2020, when he stopped Donald “Cowboy” Cerrone in 40 seconds at UFC 246. He then lost two straight fights to Dustin Poirier — the second at UFC 264 in July 2021, ending in a doctor stoppage after McGregor broke his left tibia and fibula. The injury required surgery and kept him out for nearly five years. During that time he dabbled in acting (the 2024 Amazon film Road House), launched businesses, coached on The Ultimate Fighter, and repeatedly teased a comeback.

The Comeback That Wasn’t: UFC 329 (July 2026)

On July 11, 2026, McGregor finally returned at UFC 329 in Las Vegas, rematching Max Holloway — the man he’d beaten by decision back in 2013. The fight ended after just 69 seconds. McGregor attempted a flying switch kick, landed awkwardly, and immediately crumpled with a torn right ACL and damaged meniscus. Referee Mike Beltran waved it off, giving Holloway the TKO victory. McGregor’s record fell to 22-7. “I’m devastated. I didn’t have any injuries before the fight. This came out of nowhere. I’m beyond depressed. I can only describe it as hell,” he wrote on X. He has targeted a return in 2027 for the final fight on his UFC contract.

Dating History and Affairs

Before Dee Devlin, McGregor’s dating history is not publicly documented. Devlin — born August 9, 1987, in Walkinstown, Dublin — has been by his side since before he was famous, working as his accountant, manager and business partner as his empire grew. There have been no confirmed reports of affairs or other relationships during their 18-year partnership. McGregor has been devoted to his family throughout his turbulent career, regularly posting photos of all four children at his fights.

Controversies

McGregor’s career has been marked by a series of legal and personal controversies that have repeatedly threatened his brand:

• Dublin pub assault (April 2019): Video emerged of McGregor punching an elderly man in a Dublin pub after the man refused a drink of his Proper No. Twelve whiskey. McGregor pleaded guilty to minor assault and received community service.
• Bus attack (April 2018): McGregor attacked a bus carrying UFC fighters at the Barclays Center in Brooklyn, throwing a dolly through a window. He pleaded guilty to felony assault and was sentenced to community service and anger-management counseling.
• Civil rape verdict (November 2024): A Dublin civil jury found McGregor liable for sexual assault of Nikita Hand, awarding approximately €248,000 in damages. McGregor denied the allegations and appealed; Ireland’s Court of Appeal dismissed his appeal in July 2025, and the Supreme Court refused further appeal in December 2025.
• Commercial fallout: After the civil verdict, Proximo Spirits removed McGregor from Proper No. Twelve marketing. Major Irish retailers — Tesco, Musgrave, BWG Foods and the Barry Group — pulled his alcohol brands from more than 1,000 outlets.
• Presidential bid (2025): McGregor announced a run for President of Ireland under the “Independent Ireland” platform, but was ruled ineligible by the courts after failing to secure the required nominations.
• Lobov whiskey lawsuit: Former friend and sparring partner Artem Lobov sued McGregor claiming 5% of Proper No. Twelve proceeds (~$30 million). The case settled on April 15, 2026 — the day trial was to begin — with terms undisclosed.
