Holloway is two fights removed from a failed featherweight title bid against Topuria, the only person to knockout Holloway in 35 professional fights. Topuria and Holloway subsequently moved full-time to lightweight. Topuria knocked out Oliveira to win the vacant 155-pound title, and Holloway defended the BMF belt against a retiring Poirier.

Poirier is deemed by many as the best UFC fighter never to win an undisputed title. After beating Holloway to win the interim lightweight title, he was submitted by regular champion Khabib Nurmagomedov while trying to unify the belts.

However, a recent announcement from Poirier himself suggests that he might not be done with the UFC just yet. Hearing that Poirier is returning to the UFC just a couple of weeks after competing in his last fight might be slightly confusing. Fighters have decided to come back despite retiring, as we've seen from people like Conor McGregor before.
