Yeah he may well have been a medalist, although as we've seen with Khan and Audley it doesn't mean a whole lot.

Certainly Johannson is only known to the general public in relation to his trilogy with Patterson, but I believe Floyd won overall so doesn't count.

I think it's Mayorga that's the best example so far. Forrest was a top 10 p4p, maybe even top 5 at the time and Mayorga smashed him in a huge upset. But to then get the win a second time, there arn't many underdogs that have done that.

I'm not familiar with Ivan Robinson though so he may well be a good example.

I also liked Maskaev Rahman as well, I mean both those defeats were brutal for Hasim, and both fights he was expected to win.

It's a really interesting question though I think, I mean I can think of loads of upsets like Baldomir Judah, Wlad Sanders, Tyson Douglas etc but none of them followed it up with a win a rematch.

There probably can't be many who have achieved this.........
