The GWS Giants say they will stand by Shane Mumford and offer him support after footage emerged of the ex-GWS and Sydney ruckman snorting a white powder.
The AFL is aware of the incident, which occurred three years ago, and is conducting an investigation.
The Giants, his current employer, confirmed the shirtless man in the video was Mumford.
“Shane has expressed deep remorse, embarrassment and distress in relation to his actions,” The Giants said in a statement.
“He understands he has let himself, his family and the club down and caused great embarrassment to those around him.
“The club understands the incident took place in 2015 shortly after Shane had suffered a season-ending injury in round 11 that year.
“The club is extremely distressed by the footage and views Shane’s actions as completely counter to the club’s values.”
Mumford, who won a premiership with Sydney in 2012, worked as a part-time GWS ruck coach this season after retiring in 2017 due to a foot injury.
But the 32-year-old was preparing to make a possible shock AFL comeback next season to bolster the Giants’ ruck stocks following the loss of versatile tall Rory Lobb.
GWS indicated it would stick by Mumford, but it was unclear whether the revelation had jeopardised his push for a second stint in the AFL.
“The club is disappointed in Shane’s choice of actions at this time and also understands that Shane requires a level of medical support, with his health and wellbeing in mind,” the statement said.
“The club will be working with Shane to ensure he engages in a rehabilitation program along with a range of other measures.”
