Collingwood forward Jordan De Goey is out of their preliminary final and is in a race against time if they make the AFL grand final.
De Goey suffered a confirmed hamstring strain in Friday night’s qualifying final win over Geelong, his first game back after more than a month out with another hamstring injury.
Teammate Levi Greenwood also has a confirmed anterior cruciate ligament in his left knee, meaning he is sidelined until well into next year.
