Smaller clubs could fold if the coronavirus forces them to shut up shop, Dagenham managing director Steve Thompson fears.
The Daggers' National League game at Woking was postponed on Saturday after two of their players and two members of staff started showing signs of the virus.
The league has tried to continue despite the EFL and Premier League postponing all games for three weeks, with six fixtures going ahead on Saturday, although five were called off.
Many, including Dagenham, rely on hospitality and events for a large portion of their income but Thompson can see EFL and National League clubs going to the wall if there is an extended break because of coronavirus.
