Former Sydney premiership player Shane Mumford has been identified as the man being filmed snorting a large amount of a white powder on a coffee table.

The video, which has been circulating on social media on Tuesday morning, shows Mumford star snorting a thick, large white line of the substance.

Mumford was joined at the location, believed to be a hotel room or apartment, by a number of other men, who begin chanting his nickname ‘Sausage” and praising him following his snorting of the powder.

Mumford then sticks his tongue out to the camera.

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

Mumford was planning to make a return to the AFL next season, after retiring from the game in 2017 due to a foot injury.

The injury was said to have been career-ending at the time, although given the progress he made over 2018 with rehab, Mumford believed he could go around again.

GWS – where Mumford was a ruck coach for the 2018 season – were said to have been seriously considering bringing him out of retirement for 2019.
