UPDATE: Herald Sun reporter Jon Ralph has named Brian Lake as the player in question.

Lake won three premierships with the Hawks, and was the 2013 Norm Smith Medalist.

He was also a two-time All-Australian with the Bulldogs.

It is believed Lake was involved at a push and shove at a bar in Japan, and could be detailed in an Osaka jail for up to 23 days without charge.

Those around the incident believe Lake was involved in the incident, although believe he did not throw a single punch.
