Brisbane Lions Chairperson Andrew Wellington has publicly backed senior coach Chris Fagan, just days after a bombshell report from the ABC raised allegations of racism from Fagan's time at Hawthorn.

Fagan stood down from his duties at the Lions late on Wednesday as the AFL conducts an investigation into the events at Hawthorn, as did incoming North Melbourne coach Alastair Clarkson.

Wellington released a statement through club media on Sunday, reaffirming Fagan's status as a role model and mentor at the Lions, stating that the club will stand by him throughout the investigation.

"Since Chris Fagan arrived at the Brisbane Lions in October 2016, he has been more than just our Head Coach. He has been a role model, a mentor, and a father figure," the statement read.

"He has played a key role in steering our Club into the strong position it's in today; integral to our success on and off the field.

"In all of my dealings with Chris over the past six years, he has always made the welfare of our players and staff an utmost priority.

"Chris has been a great supporter of all of our players and their families and has worked hard to ensure our Club provides a culturally safe environment for everyone.

"We stand by Chris as he commits himself to be part of the AFL investigation, which gives him procedural fairness, into allegations concerning historical events at the Hawthorn Football Club, where he was a former employee.

"Chris has categorically denied any wrongdoing. It has been a distressing and difficult week for Chris, his wife Ursula, and his family, as it has for many, and we strongly support his right to a fair, impartial, and independent investigative process."

Fagan is currently contracted to the Lions until the conclusion of the 2023 season.
