COLLINGWOOD'S loss to the Western Bulldogs was compounded by injuries to four key players, which left the Magpies with no available men on the bench for the last 13 minutes of the match.
Defender Alan Toovey was the first casualty after failing a concussion test, while midfielder Taylor Adams hopped off the ground early in the third quarter with a left hamstring injury.
Forward Alex Fasolo did not feature in the final quarter due to a left shoulder complaint, and the tiring Magpies could not make any further rotations when Darcy Moore succumbed to a collarbone injury soon after.
Port Adelaide will assess Jack Hombsch for hamstring tightness ahead of the Power's clash with Collingwood at the MCG on Sunday 5 June at 1.10pm (AEST).
