Kangaroos teenager Charlie Comben has been handed a cruel blow to his pre-season after sustaining a tibial stress fracture, per the club website.

The key forward/ruck utility is yet to make his debut with North Melbourne and will now face a lengthy stint on the sidelines, with the Kangaroos set to take a conservative approach in the 19-year-old's recovery.

North Melbourne football boss Brady Rawlings said the setback was a huge disappointment for the club and Comben.

โ€œItโ€™s a disappointing result for Charlie who has been working really hard to give himself the best opportunity this season,โ€

โ€œWe will take an extremely cautious approach to his rehabilitation with a view on his long-term career.

โ€œCharlie has a lot of potential, heโ€™s a hard worker, has a great attitude and we see him being an important part of our team in the future.

โ€œWeโ€™re confident that Charlieโ€™s resilient character and meticulous approach to training will put him in the best position to return to full fitness.โ€
