Jersey netball's elite side Team Jets faces a funding shortfall of £40,000 for 2019.
Changes in sponsorship mean that the side is now below the £120,000 cash pot it needs to cover the sport for the under 14, under 16 and senior sides.
Netball is the biggest female sport in Jersey in terms of participation and the side are worried about covering the cost of the current programme.
It sees players compete in the top divisions in England - a competition which helped to produce England captain Serena Guthrie, who hails from Team Jets.
The Jersey Netball Association's President Linda Andrews says the growing uncertainty about the future is a real concern.
Jersey Netball Association is also looking for a new home, as it is set to leave its Les Ormes base in 2020 after ten years at the venue.
Jersey's sports minister Senator Steve Pallet says that the road to finding a new home for the sport on the island is likely to be long - but that the States are working with the Association to find a solution.
