Boxers who were unfriendly to each other after their fight

[BKM-2010]

I saw Barrera blatantly sucker-punch Morales at a press conference so imo it's understandable that he would not shake that man's hand.

Aside from Morales-Barrera, Duran-Leonard I & II always come to mind. Duran even stated that before the first fight that he HATED Leonard. The two were polar opposites inside and outside of the ring.

I will give you the best/worst example right off the bat. James Butler sucker punching Richard Grant after losing a decision.
