Richmond pair Sydney Stack and Callum Coleman-Jones took to social media on Saturday afternoon to issue messages of apology for their breach of the AFL’s COVID-19 protocols.

"I just wanted to take the opportunity to apologise for the mistake I made," Stack said via Instagram.

"I'm very sorry, understand the seriousness of it and can do nothing now but own the consequences. I've let down the AFL, the club I love, my team mates (sic), coaches and staff, it's members and the tiger army.

"I also have let down my family, my friends and all of those who have helped me along the way."

Coleman-Jones was equally regretful, and like Stack, vowed to win back the trust of all concerned.

"I take full responsibility for what I have done and am extremely remorseful," he said.

"I've let a lot of people down including; the football club, the AFL, the Queensland Government, my friends and family, all the supports/Tiger Army, and the wider community.

"I realise what I did was selfish and had the potential to jeopardise the continuation of the competition being played in Queensland."
