Another Collingwood fan has been captured on video yelling racist comments during Friday night's AFL match against Sydney.
Swans superstar Adam Goodes has already spoken of his deep distress at being called an "ape" by a 13-year-old girl supporting the Magpies late in the MCG clash.
Footage emerged on Sunday of a man wearing Collingwood apparel screaming about indigenous players during the same game.
An AFL spokesman said he was yet to see the footage but the league had made it clear where they stand on racism.
On Saturday, Goodes received an apology from the 13-year-old girl and said while he was "gutted" by her comment, she needed to be supported and educated.
"She's 13 years old, still so innocent, I don't put any blame on her," Goodes said.
"Unfortunately it's what she hears and the environment that she's grown up in that has made her think that it's okay to call people names."
