Rugby HQ have listed their top five 'forwards gone wild' moments and it features a memorable, for negative reasons, South Africa vs Ireland game from 1998, now infamously known as the 'Battle of Pretoria'.
Players from both sides started beating skelps out of each other when Malcolm O'Kelly received a kick from Joost van der Westhuizen early on. Just watch out for what Sean Moloney calls the "latest tackle of all time" from (I think) Rob Henderson. There was an excellent look back at the game from David Kelly in the Indo five years ago.
Also featured in the top five is a great reason for why hookers should not box kick.
