Racial and homophobic abuse towards four AFL players within 24 hours has prompted CEO Gillon McLachlan to call for the behaviour to stop.
The Fremantle Dockers condemned the "vile, racist and homophobic abuse on social media" of Nathan Wilson and Michael Walters on Tuesday.
Meanwhile, the Brisbane Lions reported racist comments — allegedly made towards forward Charlie Cameron — to the AFL integrity unit on Tuesday.
This follows Adelaide Crows star Izak Rankine calling out a racist message he received via social media on Monday.
"This has to stop," McLachlan said.
"It not only hurts the Aboriginal and Torres Strait Islander players targeted but all Indigenous players and players of colour across the league as well as their families, their teammates and friends.
"We strongly support all our players and condemn the racial vilification of anyone in football and anyone in the wider community."
Fremantle Dockers chief executive Simon Garlick said the abuse was "unnecessary and disgusting" and should not happen.
"Individuals that hide behind fake accounts to hurt others are pathetic and we need to be able to curb this capability on social platforms," he said.
"In the meantime, I urge fans to use this conversation to call out racist and homophobic slurs for the abhorrent and archaic discourse that it is."
Brisbane Lions chief executive Greg Swann has urged supporters to continue to call out unacceptable behaviour, after a fan made them aware of the abuse targeting Cameron.
"I'm angry and disappointed that Charlie, and we as a footy club as well as an industry have to constantly deal with this," he said.
"We want to take a strong stance against this happening and support any repercussions that the perpetrator may face."
