Collingwood duo Steele Sidebottom and Lynden Dunn are under AFL investigation for a potential COVID-19 breach, as first reported by Seven News' Tom Browne.

The league is reportedly finalising its inquiry and will announce findings soon, which could include suspensions.

Collingwood confirmed that Sidebottom and Dunn are the players being probed in a statement released on the club website.

"Collingwood can confirm that players Steele Sidebottom and Lynden Dunn are under investigation for breaches of the AFL’s return to play protocols," the statement read.

"Sidebottom and Dunn shared an Uber on Saturday evening and Sidebottom later visited a member of staff who is not living under the game’s protocols.

"The breaches were reported to the AFL on Sunday afternoon. The players were interviewed by the AFL yesterday.

"Sidebottom and Dunn will not be permitted to return to the Holden Centre until cleared to do so by COVID-19 testing."

The Magpies self reported the breaches on Sunday afternoon and the two players were interviewed by the AFL on Monday, according to AFL Media. 

It is believed that they spent Saturday night drinking with teammate Jeremy Howe, a night after the star defender suffered a serious knee injury against GWS.

According to AFL Media, Sidebottom and Dunn then reportedly caught an Uber to Dunn's house - which is not allowed under AFL protocols.

Dunn's night reportedly finished there, while Sidebottom went to former Magpie and part-time employee Daniel Wells' house afterwards, breaching protocols a second time.

Essendon pair Conor McKenna and Brandon Zerk-Thatcher, Melbourne duo Charlie Spargo and Kysaiah Pickett and Port Adelaide's Ollie Wines have already been handed suspensions this season for breaching such protocols.

The Magpies face Essendon at the MCG on Friday night.
