Collingwood duo Tyson Goldsack and Levi Greenwood have been involved in a physical altercation with ex-AFL player Nathan Djerrkura at a Northern Territory pub on Saturday night, as reported by AFL Media.

Goldsack and Greenwood were in NT for a White Ribbon Football Competition and family event earlier that day at Hindle Oval.

It is understood that Djerrkura approached Goldsack, Greenwood and a third man with the pair which led to the incident.

The Magpies duo and third man left the pub immediately afterward with no serious injuries.

An NT Police spokesman confirmed a man was arrested at the venue on Saturday night.

"He has since been released and issued an infringement for disorderly behaviour," the statement read.

"Police have not received a complaint and are therefore not investigating an assault."

A Collingwood spokesperson told AFL Media that the club would speak to Greenwood and Goldsack when they return to Melbourne.

Djerrkura played 25 games for Geelong and the Western Bulldogs between 2007 and 2012.
