Perth Glory forward Mile Sterjovski is expected to be sidelined for two weeks with an ankle injury.

The 31-year old was injured in a heavy challenge by Newcastle Jets defender Ljubo Milicevic in the Glory's 1-0 win at nib Stadium on Saturday night which forced him off the pitch in the first half.

An MRI scan yesterday confirmed that Sterjovski has damaged an ankle ligament which should force him out of next week's away clash with Melbourne Heart and the round 5 home game against Wellington Phoenix.
