The Collingwood-listed player has trained this week alongside his younger brother Nick at the Hawks in a move which has the blessing of ASADA, the AFL and the Magpies.

His former coach at Wodonga Raiders where the Sydney Swans initially drafted him as a rookie at the end of 2016, Daryn Cresswell, is also coaching Wangaratta Rovers this season.

The substance detected by ASADA was an illicit drug and when found on match-day is regarded as performance enhancing.

The maximum penalty is a four-year ban from football, but can be reduced under certain circumstances.

Collingwood is understood to be supportive of Murray training with Wangaratta Rovers for personal welfare reasons on the proviso all conditions of his case laid down by ASADA are met.

He could be still training with Collingwood.

But all parties including his management are in agreeance if he was training with the Magpies he would be subjected to unwanted scrutiny and pressure ahead of the final determination by ASADA.

Murray was traded to Collingwood at the end of 2017 without playing a senior match for the Swans.

He made his AFL debut in round one last season with his 13 matches for the Magpies including the Anzac Day clash at the MCG.

Murray was nominated for the AFL Rising Star award in round three.

He played his most recent senior match in round 21 against Brisbane and subsequently missed the Magpies' charge to the grand final.
