The kid did hit his head on the ground but he lay motionless for about 30-60 seconds which I reckon he was initially stooging for a free kick, then realised nothing was coming his way so stayed motionless because he was embarrassed. When the trainers finally arrived they patted him on the back and he instantly stood up and ran off the ground without showing any signs of bother.
Therefore it was a ‘nothing here move on moment’, so Christian will cite him and the AFL politburo will give a week, guaranteed
