Ok, since it's now "tomorrow", I guess it's my turn... so here we go (and I hope Ezzard won't hate me!):

I was once a world champion with more than 100 pro bouts under my belt.
In my last fight I avenged a previous loss - which enabled me to retire with the proud claim of having avenged every defeat I had ever suffered in a pro ring.

Who am I?

Dulio Loi.

Yep... and I can see, you have already posted the next question... which has already been answered. Man, things are really moving here!
