Heritier Lumumba has taken yet another swipe at former club, Collingwood in a Facebook post in Thursday morning.

Following news that emerged last week that Lumumba has hit out at his former side as a “boys’ club for racist and sexist jokes” in an upcoming documentary, the ex-Pie and Demon is in the headlines once again, following a social media post directed at the Collingwood Football Club.

Lumumba, who retired from AFL at the end of last season due to concussion, also criticised the AFL and the AFL Players' Association.

"The nickname ‘Chimp’, that was used during my time at the Collingwood Football Club is just one of countless examples of institutionalized racism within the AFL.

The systematic nature of racism in the AFL is evident in the operation of Recruitment and List Management departments of football clubs; the management of players by agents; the AFL’s failure to protect its highest profile Aboriginal player, Adam Goodes, from ongoing racism that effectively ended his career; the AFL and Collingwood Football Club’s failure to sanction or penalise Eddie McGuire following his comments comparing Adam Goodes to an ape.

Furthermore, players like Joel Wilkinson, who have been direct victims of racism, have been threatened and silenced when their experience disrupts the AFL’s comfortable multicultural narrative, along with having their recruitment and careers jeopardized for speaking out.

It is disappointing that so far the Collingwood Football Club have chosen to minimise and dismiss my experiences. I’m further disappointed, but not entirely surprised, that the AFL and the AFL Players’ Association have made no comment whatsoever about the issues I have raised.

I am grateful to the players and former teammates who have stood by me and confirmed my story like Shae McNamara. I also recently spoke to Leon Davis, who said “Your experiences of racism at Collingwood were a continuation of my own experiences at the club. I stand side by side with you.”"

Lumumba played 199 games with Collingwood from 2005 to 2014, before falling out with the club and moving to Melbourne, where he played 24 games in two seasons.
