There are hopes that next Tuesday's game between Hereford and Kettering will go ahead.
Because of a Covid incident at Kettering their game against Southport, set for this afternoon, was postponed.
However it's thought some Kettering 'staff' watched the game at Alfreton this afternoon.
"As far as I was aware they were isolating but a couple of them have come here today, so very strange," said Hereford manager Josh Gowling.
