Dustin Poirier has been told by UFC rival Islam Makhachev he is only moving up to welterweight because he won't be a lightweight champion.
Poirier came up short on his bid to win the lightweight belt when he was choked out by 155lb champion Charles Oliveira at UFC 269 last December.
It marked the American's second chance to win the title, having been submitted by Khabib Nurmagomedov when he first competed for the belt in 2019.
