8. Setanta O'hAilpin v Cameron Cloke
In 2009, Carlton teammates Setanta O'hAilpin and Cameron Cloke were involved in a bust-up after O'hAilpin king hit and kicked Cloke during an intra-club match. The unprovoked attack led the tribunal to suspend O'hAilpin for four games, charging him with a level four striking offence and a level two offence for laying in the boot.
Whilst the Carey / Stevens situation was ugly and involved the AFLโs highest profile player it occurred in the off-season and the 2 never played for the same team again so it was hardly a long running feud within the confines of the club. iโm surprised you never included the likes of Andrew McLeod / Tyson Edwards and Gary / Steven Hocking. Both combinations played 200+ games in the same team and rarely spoke to each other and had major personal disagreements with each other.
