AFL media personality Kane Cornes has praised Collingwood players for their open letter in response to the racism report that found systematic racism in the Magpies culture.

120 players from the Collingwood men's, women's and netball teams released the letter which apologised for past racism at the club.

Cornes said it was a landmark step towards acknowledging their past mistakes and moving towards an inclusive culture.

“The letter was well written and it was the right thing to do,” Cornes said on SEN SA Breakfast.

“It's been signed by 120 players and staff from Melbourne, sorry is the first word and that's a big tick – it's the first word that should have come out of Eddie McGuire's mouth when he faced the media and called it a proud day for the football club.

“They've done the right thing there, I think it's a landmark moment for the football club."

Earlier in the week, Collingwood President Eddie McGuire drew criticism for labelling the release of the report as a "proud day for the club" because the club had the bravery to commission it.

Since the press conference, McGuire has been urged to stand down by Greens senator Lidia Thorpe for being passive in his response to racism claims at the club.

“As the head of the club, Eddie not only oversaw these issues – he's been part of the problem,” Senator Thorpe said.
