A BRISBANE supporter who racially vilified Allen Christensen on social media will be barred from ever becoming a club member unless they undertake "appropriate cultural awareness training".

The comment, made via a private Facebook group, was made during Saturday night's win over North Melbourne.

The club was made aware of it on Sunday and released a statement on Monday, saying the comment would not be tolerated in any form.

"It has been established that the individual, while they identify as a Lions supporter, is not a member of the club," the statement said. 

"The individual will be barred from becoming a member of the club in the future, unless they can demonstrate they have participated in appropriate cultural awareness training and the club is convinced they have learnt from this terrible mistake."

Brisbane chairman Andrew Wellington described the comment as disgraceful and completely at odds with the club's values.

"Racism stops with us and has no place in our society," Wellington said. 

"The club works strongly with our stakeholders including Deadly Choices and Multicultural Development Australia to educate our players, staff and community on respect in our society, and this will only strengthen our resolve to continue those efforts."

Christensen also released a statement. 

"In a week where the Adam Goodes film has been shown nationwide and on the back of NAIDOC week, myself and the club will keep striving to educate the wider Brisbane and AFL community that these comments are not acceptable," he said.

"These sort of comments have a great effect on families, teammates and players around the league and the country.

"We as a game have come a long way, but 'OK' is not good enough and I know highlighting this type of racial stereotyping will all keep us going forward as a community."
