Yeah Vargas is a popular one and that was a nice little mouse Chico had after Castillo.

Also Rahman had it pretty bad when he grew a second head versus Holyfield.

And there was a guy in the first world cup of boxing, I think he was fighting Vorapin (could be wrong), but he had an intense swelling that went from like his ear to his nose and up his forehead. He was getting it pounded with every punch and each time he would wince in pain but the fight was never stopped. That was a bad one.
