Jan 18, 2021 Paid in Full. The mantra incoming UFC 257 headliner, Dustin ‘The Diamond’ Poirier beats his drum to. Looking to right a six-year-old wrong this Saturday night in Abu Dhabi, the Lafayette bruiser welcomes past rival, ‘The Notorious’ Conor McGregor in a potential lightweight title eliminator. Spoils are massive for the victor, particularly if either shine, with current undisputed titleholder, Khabib ‘The Eagle’ Nurmagomedov dangling the carrot of a potential return if he witnesses “ blood and guts” war with his past opponent. Eager for a battle of attrition, the American Top Team staple has made remarkable alterings to his approach, embarking on a fantastic run of his own following his UFC 178 knockout defeat to McGregor — which also spelt his final featherweight foray.
