Conor McGregor is an Irish professional mixed martial artist who is currently signed with the ‘Ultimate Fighting Championship’ (UFC). He is the former ‘UFC’ lightweight and featherweight champion. Over the course of his career, he has competed as a featherweight, lightweight, and welterweight participant. Also a skilled professional boxer, he has achieved most of his victories due to knockouts or technical knockouts via punches. He started his mixed martial arts (MMA) career in 2008, and within a few years won two titles—Cage Warriors Featherweight and Lightweight Championships, which he held simultaneously before he vacated them to sign with ‘UFC.’ He is known for being in the biggest pay-per-view draw in MMA history, and he lives an extravagant lifestyle. In 2016, he got into ‘Forbes’ top 100 highest-paid athletes list—the first MMA fighter to do so—and ranked 85th on the list. He was injured during a bout with Max Holloway which kept him out of action for ten months. After winning the lightweight championship, he took some time off from ‘UFC’ prior to the birth of his first child in May 2017.
