A video appearing to show Port Adelaide forward Jack Watts snorting a white substance has surfaced on Facebook.
In the video, Watts appears to be snorting a white substance off a woman's chest at a public festival. It is unknown when the video was taken.
The Herald Sun has spoken to Watts' agent Paul Connors, who has categorically said the substance was not cocaine.
Connors said it was a harmless "peppermint" tobacco mix, that commonly appears at Oktoberfest events.
The 27-year-old joined the Power as a free agent last year, after being drafted at pick one by Melbourne.
