COLLINGWOOD defender Nathan Brown will find out the extent of his hamstring injury when he receives results of scans on Monday afternoon.
The premiership defender ended Saturday's VFL game on the bench and had his hamstring iced after the game.
Brown, a member of the Magpies' leadership group, had been dropped from the senior team after struggling in the opening six games of the season.
The 27-year-old has played 120 senior games and is a free agent at the end of 2016.
Key forward Travis Cloke missed the VFL game after experiencing back problems.
The out of form forward played two VFL games after being dropped ahead of the Anzac Day clash.
The Magpies are also uncertain about the extent of the shoulder injury Ben Reid suffered when he copped a heavy hit against Carlton, while Tim Broomhead was sidelined for much of the second half against the Blues when he hurt his ankle after landing heavily from a marking duel.
Both players finished the game on the ground but will be monitored early in the week.
