In the early days of Straight Blast Gym (SBG) in Ireland, head coach John Kavanagh faced an unexpected challenge from a brash newcomer who would later become one of MMA’s biggest stars. The incident, which occurred in 2006, involved an 18-year-old Conor McGregor and demonstrated how the future UFC champion had to learn some hard lessons about gym etiquette and respect for training partners.
According to Kavanagh’s book, he had to take it up on himself to reign in a young McGregor at one point.
McGregor arrived at SBG through his connection with Tom Egan, immediately making his presence known by declaring himself a future UFC champion. While confidence wasn’t lacking in the young fighter, proper gym etiquette was. In his very first sparring session, McGregor’s eagerness to prove himself led to him dropping Owen Roddy, an established professional fighter, with a powerful body shot.
Coach Kavanagh initially let this aggressive behavior slide, understanding the newcomer’s desire to make an impression. However, what happened next crossed a line that couldn’t be ignored. After his session with Roddy, McGregor paired up with Aisling Daly, one of SBG’s first female fighters. Daly, who had initially struck Kavanagh as a “quiet, nerdy person,” had proven herself capable of training alongside the men in the gym.
When word reached Kavanagh that McGregor had dropped Daly with another body shot, leaving her in tears, the coach knew immediate action was required. “Right, Conor, I’m next,” Kavanagh declared, stepping into the ring himself to deliver a necessary lesson in gym culture and respect.
The ensuing sparring session was less about technique and more about teaching. Kavanagh took McGregor down and, in his own words, “beat him up” until the message was crystal clear: these people were teammates, not opponents. The lesson seemed to hit home, with McGregor acknowledging afterward, “Yeah, I deserved that.”
This formative moment in McGregor’s early career highlights the importance of gym culture and the role that experienced coaches play in molding not just fighters’ skills, but their character as well. The incident served as a turning point for the “scrapper” who walked into SBG that day, helping to shape him into the professional fighter he would become.
