North Melbourne forward Ben Brown has suffered a setback in his pre-season, undergoing a minor knee operation on Thursday.

The 24-year-old landed awkwardly at training last week, resulting in swelling in his knee. He subsequently underwent a "wash-out procedure".

Brown will miss around a fortnight of training, the club confirmed on Friday.

โ€œIn terms of seriousness, specialists feel this is at the very low end of the spectrum,โ€ senior performance consultant Steve Saunders told the club's website.

โ€œThe procedure should maximise Benโ€™s remaining preseason and outcomes for his knee long term.

โ€œWe could have managed the issue as it was without surgical intervention, but given the time to round one, we felt it was best to involve a specialist and take this course of action."

Brown's injury follows news that Majak Daw will be sideline for a month after scans revealed a tear in his meniscus late last week.
