Former Collingwood defender Heritier Lumumba has lashed out at the AFL and Collingwood Football Club, labelling their response to the damning Do Betterย report as "shameful".

Lumumba took to Twitter to express his frustrations with AFL Chief executive Gillon McLachlan and Collingwood president Eddie McGuire not fronting the media following the review into the club's systematic racism claims.

"The people at the top need to front up and face the media, instead of getting others to take their hits," Lumumba posted in response to Magpies' board member Jodie Sizer and AFL inclusion and social policy manager Tanya Hosch.

"It's shameful that both Collingwood and the AFL have forced two Black women - Jodi Sizer and Tanya Hosch respectively - to front the media for the past week, instead of Eddie McGuire and Gillon McLachlan.

"Systemic issues start at the top. The people at the top need to front up and face the media, instead of getting others to take their hits. This is pathetic leadership and a clear case of cowardice.

"Jodi Sizer has only been at CFC for 2 years. Why should she have to answer for McGuire's 20 years of failures, with respect to racism? These Black women should not have to answer for the incompetence & indifference of privileged white men with major institutional power."

Lumumba chose not to be involved in theย Do Betterย report but has made past allegations suggesting Collingwood hosts a racism problem within it's culture, namely conjuring the nickname "chimp" for Lumumba.

Collingwood footballers and netballers released a statement last week to apologise for past discriminatory behaviour and promised to make amends of the claims made from the club review.
