Day suffered a dislocated hip during the first quarter of the match and was stretchered off the field and taken straight to hospital.
The big man was jostling for position while running towards the ball alongside Brisbane defender, Jack Frost, when he collapsed to the ground.
The 24-year-old was in extreme agony and was given pain relief on the ground.
