Collingwood have confirmed Steele Sidebottom and Lynden Dunn are currently under investigation for allegedly breaking strict AFL COVID protocols.
The club said both Sidebottom and Dunn shared an Uber last Saturday night, which breaks the current rules all players are forced to abide by.
"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 protocol," a Collingwood statement read on Tuesday night.
"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."
It's a major distraction for the Pies, who will face Essendon on Friday night.
The Bombers will welcome back Conor McKenna, after he was allowed to leave quarantine early following his positive COVID-19 test on June 20.
