Brighton boss Graham Potter has dipped into his pocket to help Ostersunds' rescue fund.
The Swedish club is battling to stay financially afloat this season.
Former OFK coach Potter has contributed to the club's fighting fund to pay back a tax debt.
A statement on the club's Facebook page read: "OFK's former coach Graham Potter, together with his colleagues at Brighton, Bjrn Hamberg, Billy Reid and Kyle Macaulay, went in and made a big contribution to FK in our 'I believe in this' campaign.
"A big thank you to these four coaches for helping us!"
