Patrick Voss fails to overturn a three-match suspension for a high hit on Richmond's Nick Vlastuin that left the Tiger defender bloodied and facing potential injury.
"The extent and nature of the force of impact and the fact that full force of the impact struck Vlastuin's face leads us to find that the potential for more serious injury was real," Tribunal chairman Jeff Gleeson KC said.
"The video evidence shows quite clearly that this was a forceful blow to the head, and one that experience and common sense indicate could have readily result in a concussion."
