Get them in: Sam Frost, Angus Brayshaw and Mitch Hannan all performed strongly for Casey in a practice match against Frankston on Good Friday and will come into the selection frame for Saturday's game against the Roos. Billy Stretch is another pressing hard to play.

Under the pump: With Frost a chance to come in and play on Jarrad Waite or Ben Brown, Josh Wagner might find the going tough to keep his spot. Tom Bugg, James Harmes and Christian Salem, who did not look like himself after a hefty knock against Geelong the previous week, may find themselves under pressure.

Medical room: Youngster Bayley Fritsch copped a knee to the abdomen against the Lions but played out the game and should be fine to face the Roos. A few others will be monitored but there are no real issues on the injury front.

Verdict: Frost is a big chance to earn a recall with North Melbourne's size up forward, possibly for Wagner. Bugg applies good pressure but Hannan, who booted two goals for Casey, is a little more polished in front of the big sticks.
