The Belgian top flight announced it was ending its season, with Club Brugge declared national champions. The league stated it was acting on advice from the government and public health experts in the country.
A letter from the presidents of European governing body UEFA, the European Club Association and the European Leagues group to national associations, leagues and clubs said cancellation should be a "last resort" and warned clubs from competitions deemed to have been cancelled prematurely could be barred from next season's Champions League and Europa League.
"Since participation in UEFA club competitions is determined by the sporting result achieved at the end of a full domestic competition, a premature termination would cast doubts about the fulfilment of such condition," the letter said.
