Nah, he won't retire. Maybe out for a year or so (no, I don't mean the KO) and then call it a comeback.
Fury will be a fixture in the heavyweight division for the next 15 years. If he doesn't win the title in his next fight, he'll win it in a year or two. He'll probably spend some time in jail (for some relatively minor offences). He'll probably quit for a while in a failed bid to become a singer. He'll be a huge celebrity. He may not fight every year ... and some years he may only fight once. But Tyson Fury is going to be around for a very long time. Until around 2030. And, during some of that time, or maybe a lot of it, he'll be a heavyweight champion.
This...he will get destroyed by Wlad...say he's not as good as he thought he was. Retire. Fast forward 9months or so..his bank balance will be dwindling and his ego will have started to heal...and he'll announce his comeback. At this point Anthony Joshua will be fighting higher level opposition. Furry will trim off some fat (leaving lots still wobbling on him) comeback having a few fights and then after a few cans are beat he'll have a big money domestic fight with Joshua...then get KO'd again. Watch n see...I've seen teh futurz. :bbb
Wlad's all like. Fee-fi-fo-fum, I smell the blood of an Englishman, Be he alive, or be he dead I'll grind his bones to make my bread.:deal
Too many big matches for Fury available for Fury to retire. He has A lot of money ahead of him. If he loses to Wlad. He has Joshua, Price and Wilder. All would make a decent buck for him.
