MELBOURNE forward Ben Brown has chopped off his famous curly locks to raise important funds for Challenge, a not-for-profit organisation that supports families and children living with cancer.

Challenge is a charity close to Brown's heart, with his 17-year-old cousin Grace having been supported by the organisation during her long-term leukaemia battle. 

Fans rallied around the 30-year-old as his hair was chopped during Melbourne's family day on Saturday.

Supporters can still show their support for Brown's fundraiser here.
