Super/big fights between two undefeated fighters?

Pretty Boy - Pacman (since *******s claim he is undefeated)

Leonard Vs. Benitez

 

Chiquita had a loss going into the Carbajal fight - Rolando Pascua had ko'd him if I remember correctly.

 

Thanks for your contribution.

 

Good eye, I don't even remember that fight.. lol

Zarate Vs. Gomez

 

Duran v Marcel

 

I'm not sure if they're big enough to qualify but I'll throw out Tito's fights with Carr, Campas and Reid.
