North Melbourne midfielder George Wardlaw has been cleared of any serious hamstring injury, although scans have confirmed a low-grade strain.
Wardlaw left Friday's match simulation with a hamstring complaint in his left leg, and has a history of troublesome soft-tissue issues.
Wardlaw played just 13 games last year due to concussion and hamstring problems, and 39 across his three seasons at Arden Street.
The powerful Roo will be back to full training over the next fortnight, and is still in the frame for the club's Round 1 clash against Port Adelaide.
However, the news isn't as fortuitous for veteran Luke McDonald, who suffered a sprain to his right wrist.
McDonald will be in a splint for the next month, but will be able to train at near full capacity, albeit with slight limitations.
It comes as draftee Blake Thredgold is looking at a six-month layoff after suffering a Lisfranc injury last week.
The six-month timeframe is consistent with Melbourne premiership defender Jake Bowey, who suffered the same injury in December.
Thredgold has been sighted scarcely on the track in recent times, with the club confirming to Zero Hanger of the injury.
The trio will be absent from the club's match simulation against Melbourne on Friday, February 20, at Casey Fields.
North Melbourne will have an official practice match fixture against Collingwood on Sunday, March 1, at Mars Stadium in Ballarat.
