In a statement issued this afternoon, the league said
"The Football Association has told the leagues at our level that it is up to the leagues themselves to decide their own position regarding playing fixtures at present.
We have today been contacted by clubs that have players and personnel who are self-isolating and one case of a confirmed virus.
We have therefore decided to postpone all matches in the Thurlow Nunn Football League with immediate effect. This therefore also includes matches in the Reserve Division and the Thurlow Nunn Youth League.
The situation will be reviewed on Monday 30th March 2020 but even if the decision was then taken to restart, no games would be played in any of our competitions until at least Saturday 3rd April 2020.
This decision has been taken with the best interests of players, match officials and club personnel to the forefront and I hope that everyone can understand that this both reduces risk and brings some certainty to the situation."
