North Melbourne will be without Mason Wood for up a month with the talented forward suffering a hamstring injury against Essendon last weekend.

Wood came from the ground in the last quarter with North's medical team confirming a strain. 

Meanwhile Billy Hartung will be forced to sit out the next month-or-so after injuring his hamstring a week earlier in the game against the Bulldogs.

However, no time-frame has been set for veteran forward Jarrad Waite. The club will update his return time once the 35-year-old has commenced a running program.
