Jack Ziebell looks set for another stint on sidelines after injuring his hamstring in North Melbourne's 54-point loss to Richmond last night.
The 29-year-old suffered the injury early in the first quarter and sat on the bench for the rest of the game.
It was his first game back from the same injury he suffered against Hawthorn in round 4.
The Kangaroos will come under scrutiny for whether they rushed Ziebell back from injury.
Two weeks ago Rhyce Shaw admitted he made the "wrong call" to recall Ben Cunnington from a back injury, which is reinjured in the Kangaroos loss to the Western Bulldogs.
After the game Shaw said Ziebell's injury was a case of "bad luck" instead of an issue with their handing of injured players.
"We are assessing all the time and I thought we did a really good job after the Ben Cunnington incident," Shaw said after the game.
"Again, I’ll take responsibility for that and I thought we learned a lot from that.
"We went forward, and I think the Jack scenario is a bit of bad luck to be honest."
"He was pretty much right to go last week but we took the cautious route and it's ended up like this. It’s a bit of bad luck for Jack."
