The AFL say a failure by umpires to notice the sickening concussion suffered by Collingwood forward Lachie Schultz was the reason behind why the game was allowed to continue.
Schultz was left prone on the ground after copping a shoulder to the head while tackling Dockers' defender Jordan Clark in Collingwood's 15.7 (97) to 12.11 (83) win in Perth on Thursday night.
