Several fans claimed that they initially confused him with Dustin Poirier. Poirier competes in the lightweight division, whereas Vettori competes at middleweight.

"Thought it’s Dustin Poirier," wrote @mohamad_touray on Instagram.

Another individual hailed Vettori's professionalism, pointing to his last fight when he agreed to a light heavyweight contest following Paulo Costa's weight issues.

"Marvin earned my forever respect as a Fan and Fighter when he beat tf out of a heavyweight Costa when he still decided even after cutting himself, to fight Costa even after he failed to make weight twice and Big man Marvin won, The real hulk of Middleweight," wrote @coby_stark.
