Kind of like any AFL umpire that gets bumped and falls over like he's been shot in the brain...
Particularity the one from the weekend just passed, can't remember what game it was but after the center bounce he copped a slight knock from behind and went down like a dead man, stayed there for 5 or so seconds and then got up and appeared seriously shaken....
Unlucky for him they zoomed in on him when he was on the ground and he looked fine, looking around like a hurt child waiting for attention..
If anyone finds the video of that or similar incidents, please do post them up.
