4. Richard Loe
Known as The Enforcer, All Blacks prop Loe had something of a reputation.
In October 1992, his actions caught up with him when he was found guilty of deliberately inserting his fingers into the eyes of Otago full-back Greg Cooper “with considerable force” during the national championship final.
3. Calum Clark
This one still makes me wince. Northampton flanker Clark was found guilty of intentionally hyper-extending and breaking the arm of Leicester hooker Rob Hawkins during the 2012 LV cup final. The ban was initially for 64 weeks, but was halved due to his guilty plea.
