Vision has emerged of retired AFL premiership ruckman Shane Mumford snorting white powder off a coffee table.

Mumford, who played a total of 172 AFL games for Geelong, Sydney and Greater Western Sydney, was shirtless and sitting in front of five lines of a white substance.

He was then filmed snorting the thickest line, much to the excitement of his friends who can be heard chanting his nickname “Sausage” several times.

The 32-year-old is still employed at the Giants as a ruck coach and is understood to be considering a comeback next season.

GWS released a statement on the incident, which they believe is from three years ago.

“The Giants are aware of an incident, and associated video footage, regarding Shane Mumford from three years ago,” the statement read.

“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.

“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 well-being in mind. The club will be working with Shane to ensure he engages in a rehabilitation program along with a range of other measures.

“Shane has expressed deep remorse, embarrassment and distress in relation to his actions. He understands he has let himself, his family and the club down and caused great embarrassment to those around him.

“The club has kept the AFL informed of this matter.”

An AFL spokesman told the Herald Sun: “The AFL is aware of a video being circulated and we are investigating the matter.”

More to come.
