He waa gone for 3 yeara but i think he was only stripped after his 3rd attempt at a comeback fight was canceled/postponed. Dana was pretty adamant about not stripping him for some reason up until that point.
Dana and his arbitrary reasoning for stripping this or that champ is always hilarious and the politics involved with the interim titles…
“Cruz, sure buddy, just hang on to that official title for four, five, six years, no problem, whatever you want, I’ll send you some of my driveway Vegas snow and you and the belt can have a nice Christmas” Dana White
“Ngannou, you son of a bitch, you have had the title ten minutes, we are gonna have an interim title fight with Gane and Lewis just to make you sweat and if you don’t get your ass in there and fight the winner in a champ vs champ fight and re-sign with us for forget about that Fury thing then we are gonna have issues, pal” Also Dana White
