Boyd smashed Daryl Brohman's jaw and ended his career with a premeditated elbow. Got 12 months, wasn't back long and then picked up a 15 month suspension for eye-gouging.
At the time Jim Comans was on a purge to clean up the game in Australia, and Boyd gave him the perfect opportunity to put down a marker. If you watch some of the NSWRL stuff from the pre-Comans period, it was like Mad Max. Knees and elbows flying in everywhere, players being king hit and taken out off the ball.
