GWS has lost forward Sam Reid to concussion in their game against Collingwood at Spotless Stadium.
Reid was crunched in a tackle early in the second half and taken off for the 20-minute concussion protocol.
He failed and was taken out of the game at half time.
It’s a tough blow for the Giants given they’d already lost key back Aidan Corr to a head knock in the first ten seconds of the game.
They will have to play the entire second half with just two players on the bench.
GWS trail the fast-starting Pies at half time, 8.5 (53) to 8.6 (54).
