jose napoles vs. billy backus
floyd patterson vs. ingerman johanson
Lennox Lewis comes to mind. He was knocked out by Oliver McCall and came back to stop McCall and make him cry. He was also knocked out by Jason Rahman and came back to knock him out in the rematch.
Lenox Lewis vs Hasim Rachman
My pathetic mind can't think of anyone else :/
Floyd Patterson vs. Ingemar Johansson
Terry Norris vs Simon Brown
Lennox Lewis vs. Hasem Rahman
Miguel Cotto vs. Antonio Margarito
Jose Luis Castillo vs. Diego Corrales
Just to name a few.
The best one I saw was Patterson and Johanson.
Ingmar knocked out Floyd in the first fight, and in the rematch Floyd stiffed Ingmar and he was lying on the mat with his foot twitching rapidly after being counted out.
