In a surprising turn of events within the UFC community, Conor McGregor has rekindled an 11-year-old rivalry by resurrecting his infamous “pea head” insult toward Dustin Poirier. This came as Poirier announced his retirement following UFC 318, marking the end of a storied career and a long-standing feud between two of the organization’s most prominent fighters.
McGregor’s final jab at retiring rival
As Dustin Poirier laid down his gloves in front of his hometown crowd after a hard-fought battle against BMF titleholder Max Holloway at UFC 318, McGregor couldn’t resist taking one last swipe at his long-time adversary. The Irish fighter’s reaction appeared briefly on social media before being deleted from his X account.
Despite their bitter and contentious history, McGregor’s message contained surprisingly positive elements, acknowledging both fighters’ performances. He wrote: “We love a good scrapper in the company and them two boys are just that! Scrappers! Awesome stuff! Great fight lads, bravo!”
However, true to his provocative nature, McGregor concluded his message with “R.I.Pea head!” – reviving the derogatory nickname he first used before knocking out Poirier in their initial encounter back in 2014.
This final verbal jab represents the culmination of a rivalry spanning more than a decade, during which the fighters faced each other three times in the octagon with Poirier winning their two most recent encounters.
History of the McGregor-Poirier rivalry
The feud between these UFC stars has evolved dramatically since their first meeting. Their rivalry can be broken down into several key moments:
- First encounter (2014): McGregor knocked out Poirier, using the “pea head” insult during pre-fight promotion
- Second fight (2021): Poirier avenged his loss with a TKO victory
- Third battle (2021): Poirier won again when McGregor suffered a leg injury
- Years of social media exchanges and verbal sparring

Their relationship transformed from a one-sided verbal assault during their first meeting to a complex rivalry that helped define both fighters’ careers. The resurrection of the decade-old insult brings their competitive story full circle as Poirier exits the sport.
Respect from the MMA community
While McGregor’s message contained his characteristic sting, other UFC legends offered more straightforward tributes to the retiring fighter. Former heavyweight champion Jon Jones immediately shared his appreciation: “Congratulations on an amazing career Dustin. Thank you for the years of entertainment. Now go enjoy your retirement.”
Similarly, Islam Makhachev, who defeated Poirier at UFC 302 in June 2024, expressed profound respect: “Congratulations, Dustin. You’re truly one of the greatest to ever step into the cage. It was an honor and a privilege to share it with you.”
These messages highlight how Poirier’s impact on the sport transcended individual rivalries, earning him respect even from opponents. The contrast between these tributes and McGregor’s parting shot reflects the different relationships Poirier maintained throughout his career.
| Fighter | Retirement Message Tone | Relationship with Poirier |
|---|---|---|
| Conor McGregor | Mixed (praise with final insult) | Bitter rivalry spanning three fights |
| Jon Jones | Respectful and appreciative | Professional respect |
| Islam Makhachev | Deeply respectful and honored | Recent opponent with high regard |
Legacy of a UFC legend
Poirier’s retirement came after a five-round battle against Max Holloway at UFC 318, where he was outpointed in what many described as a highly entertaining main event. The decision to lay down his gloves in front of his hometown supporters marked the end of a career that had seen him compete against virtually every major name in the lightweight division.
Throughout his UFC journey, Poirier established himself as:
- A fan favorite known for exciting fights
- An interim lightweight champion
- A philanthropist through his Good Fight Foundation
- One of the most resilient competitors in UFC history
Even as McGregor revived their old feud with his parting shot, the broader reaction to Poirier’s retirement demonstrates the lasting impact he made on the sport. His willingness to face any challenger and his evolution from young prospect to respected veteran earned him a special place in MMA history.
As Poirier moves into retirement, the final chapter of his rivalry with McGregor serves as a reminder of the journeys both fighters have taken. While McGregor couldn’t resist one last verbal jab, the respect underlying even their contentious relationship speaks to how intertwined their legacies have become in the story of modern UFC.
