Around 9.30min into the 2nd quarter turbo. Shirt front well after the young fella got rid of the footy. Shoulder to the head and knocked him out cold. Absolute dog act. No report, no send off. In fact if you keep watching a few minutes the only one that was sent off and given 2 weeks was his older brother who came in and retaliated with some wrestling. Umpires a disgrace as they seen the incident. It should be 6+ weeks and i hope Craigieburn follow up on this.If a player was concussed and left the ground it must be on the trainers report so will be looked at by the league under the new concussion rules. What time was the incident as keen to take a look.
