The availability of several key North players will hinge on fitness tests due to be conducted later this week as the Roos prepare to take on the Lions at the GABBA.

Jack Ziebell, Todd Goldstein, Brayden Preuss and Jarrad Waite are all in doubt but will be given until the last minute to prove their fitness.

Goldstein is perhaps most in doubt with two injuries – he copped a scratch to the eye in the game against the Saints, and also received a hit to the knee late in the game.
