Dustin Poirier calls out Conor McGregor for 170 lb trilogy bout

Dustin Poirier issued a public challenge to Conor McGregor on Sunday, calling for a welterweight trilogy bout once the Irishman returns from injury. Speaking in the wake of UFC 329, Poirier made clear he is willing to come back to the octagon for one specific reason — to settle the score with McGregor at 170 pounds.

Poirier, known as "The Diamond," carries a 30-10-0 professional record and is 37 years old. The Lafayette, Louisiana native trains out of American Top Team and has long been one of the lightweight division's most dangerous competitors. A southpaw standing 175 centimeters tall with a 183-centimeter reach, Poirier lands an average of 5.24 significant strikes per minute at 50 percent accuracy, and his submission attempts at 1.2 per 15 minutes reflect a well-rounded game that extends beyond his heavy hands.

McGregor, also 37, holds a 22-7-0 record and remains one of the sport's most recognizable names. The Dublin-born southpaw represents SBG Ireland and shares nearly identical physical dimensions with Poirier — 175 centimeters tall with a slightly longer 188-centimeter reach. "The Notorious" averages 5.27 significant strikes per minute, making any potential exchange between these two an unusually even collision of volume strikers.

The pair have met twice before, splitting their first two encounters before the second fight ended in dramatic fashion. Poirier publicly urged McGregor to reach out once healthy, signaling that a move to welterweight for this specific matchup is something he would pursue.

Why it matters

• A trilogy at 170 pounds would be a rare divisional crossover event, pulling both men outside their natural weight class.
• McGregor's injury status remains the primary obstacle; no timeline for his return has been confirmed.
• Poirier's willingness to wait and campaign publicly keeps the matchup in conversation at the top of a crowded welterweight landscape.
