Wildcats vice captain Mitch Norton has been ruled out of the first five weeks of the new NBL season.
Norton continues to recover from a pre-season knee injury.
While initial scans cleared Norton of structural damage, Wildcats medical staff have opted to take a cautious approach with the two-time championship-winning point guard.
Norton hyperextended his right knee at a training session earlier this month and experienced bone bruising.
The Wildcats season begins this Friday night when they host the Adelaide 36ers.
