Reid hobbled from the field immediately but the club is hopeful that the eight-day break will aid Reid’s recovery as he sets himself to tackle the in-form Bombers.
Collingwood also remains hopeful of regaining the services of calf victims Luke Ball, Ben Hudson and Paul Seedsman.
Hudson and Seedsman were ruled out at selection last Thursday night while Ball was a late withdrawal in the hours prior to the match.
Ruckman Darren Jolly is another who may put his hand up for selection this week.
Jolly has been recovering from the minor knee surgery he underwent ahead of the round 14 clash with Port Adelaide.
All five of Reid, Ball, Hudson, Seedsman and Jolly will undergo fitness tests ahead of Sunday’s match.
In further injury news, first-year backman Jack Frost is now only a week away from returning from a knee injury.
Frost originally injured his PCL against Williamstown on 5 May.
