The AFL Players’ Association has criticised the AFL’s handling of Lachie Schultz’s concussion, saying more needs to be done to protect injured players.

Schultz was knocked out following a collision in Collingwood’s win over Walyalup (Fremantle) at Optus Stadium last Thursday, with questions raised over why play was not stopped.

The AFL initially said the umpires did not see Schultz laying hurt on the turf but were forced to retract that statement when Seven’s Agenda Setters uncovered exclusive audio of the umpires discussing the “injured player in the middle”.

AFL general manager Laura Kane said the officials “gave them the wrong information” in the aftermath, while the umpiring department are adamant they had not purposely mislead the league.

AFLPA boss Paul Marsh said the Schultz error is just the latest when it comes to handling player safety.

“It is now clear that the umpires noticed Lachie Schultz’ injury and had the opportunity to stop the play to ensure he left the field safely,” Marsh said.

“What this highlights to us is that the process of dealing with vital health and safety issues on the field is unclear, and there are many recent examples of the industry needing to better prepare everyone for when these situations occur.

“Equally, we are disappointed that the AFL failed to appropriately review a serious on-field incident but acknowledge that they have taken responsibility for this.

“We welcome the opportunity to work with the industry to continually strengthen health and safety protocols for our members.”

Schultz will miss Collingwood’s clash with Adelaide on Saturday in concussion protocols.
