Collingwood wingman Chris Mayne is doubtful for Thursday night's clash at the Gabba against the Brisbane Lions after scans showed he had a small fracture to a bone in his back as a result of the knee he copped early in his 200th game on Friday night.

The Magpies were uncertain as to how long he might spend on the sidelines as a result of the injury but said the pain associated with the injury was the biggest issue at this stage.

Mayne spent the night in hospital after watching the game from the sidelines as the Magpies wanted to check whether he had suffered any serious internal damage.

It was a bittersweet occasion for Mayne, who had his parents at the milestone match.
