Millwall supporter Conor Moorcroft is attempting to raise £1,000 for Evelina Children's Hospital London - and is asking fellow Lions fans to help him reach his goal.
Conor's nephew, Dexter, has spent a period of his life in the hospital, and the Lions fan will be jumping out of a plane, 12,000ft in the air, to raise funds.
To do this, Conor will be losing the required one stone in four months to reach the maximum weight for the jump.
Every penny raised will go towards helping other kids in need of care, so please be generous - this is for an amazing cause.
