Has a fighter ever lost the 'formality' rematch or career defining win?

Well for your first question, i think Junior Jones beating MAB was a big upset. And he proved it was no fluke beating him again over 12 rounds.

As for your 2nd question well Larry Holmes was 42 years old, and Ray Mercer was supposed to be an upcoming star. And Larry Holmes gave Ray Mercer a boxing lesson.

And im pretty sure he was the favorite from what i remember, the commentator saying. I'd have to pull out my Larry Holmes career set to make certain, but im pretty im right.

Good call on Junior Jones Ice that definitely fits my criteria. I guess Foreman Moorer could count by I don't think Moorer was ever considered a superstar, which is what I meant really, a kind of coming out party for the star elect that goes wrong, Foreman, like Holyfield in his later years has always been the star in his fights, people watching to see him win, even if not favoured to do so.

Holmes against Mercer I can't remember back that far to the general feeling of those times but it could be another example if Mercer was predicted to be the next big thing.

Well this is really going back Bilbo, and im not even sure if Floyd Patterson was the favorite. But Floyd Patterson was an upcoming star being the Olympic champion and all, then he fought the veteran Joey Maxim and lost on points. I suppose that could qualify if Floyd Patterson was the favorite.

Only if he lost to him twice. There have been many upsets in boxing but I'm talking about back to back upsets, Junior Jones defintely qualifies, as does Mayorga against Forrest (good call Snakey).

You know the kind of fight, a fighter loses to a guy in a big upset, then maybe meet either immediately or down the line when the guy has proven himself even further and the guy he shockingly lost to is believed to no threat, and routine revenge win is expected, only it doesn't happen.

If Jones had beaten B Hop tonight that would have been the kind of example I meant really, when all the momentum is in favour of one fighter, to get his legacy defining win over a legend, well past his best
