Dustin Martin was amongst a cast of Richmond players that were turned away from a primary school footy clinic.
It has been reported that the group did not have the required Working With Children Checks.
The incident occurred on Tuesday at Syndal South Primary School in Mount Waverley - the club has acknowledged.
"Players were turned away because they didn't have their Working with Children Check," said Nicki Malady Richmond spokeswoman.
"It's up to the school's discretion, but they don't actually need to have one until August 1.
"That's what they decided to do, it's a bit of a shame for the kids."
