Two players -- Paddy Ryder and Eddie Betts -- were racially abused during a match at Adelaide Oval Saturday and the AFL's players' indigenous advisory board has reacted with a powerful statement.
In the letter, signed by chair Shaun Burgoyne and seven other players, the board says it has "had enough."
"Racial vilification has been a part of our game for too long," the letter reads.
"These are more than just words and the impact these slurs have on the player, their family, their children and their community is profound.
"Despite the amazing work done in the community by our brothers and sisters, they continue to experience this disgraceful treatment.
"We want football fans to barrack for their club with passion, but shouting abuse at an opposition player and targeting their race needs to stop."
Last year a Port Adelaide member was banned after she was filmed throwing a banana at Adelaide Crows' Betts.
'It's bigger than sport'
Port Adelaide was waiting on a full report from the stadium and South Australia Police before taking further action.
The club also said it was continuing to investigate allegations that a Power supporter had racially abused 30-year-old Betts.
AFL chief executive Gill McLachlan told reporters there were "still isolated instances" of racism.
"We are going to keep tackling them, we are going to keep calling them out and we are going to keep working with our supporters and our fans. We will deal with this issue in absolute terms," he said.
"The sad thing is, this has happened to the majority of indigenous players throughout their careers," he said.
"It's bigger than sport. We've got to be there for each other as a community and as Australians. We're in this together. It doesn't matter where you are from. We're a culture that is very diverse and we have to make sure we are accepted and that's not going to bind us who we are."
