As it stands, all 33 games in National League, National League North and National League South will go ahead tomorrow.
The best supported team – Notts County, with an average attendance of 5,224 – are at home to Eastleigh.
Statement from the EFL: "The FA, Premier League, EFL and Barclays FA Women’s Super League and FA Women’s Championship have collectively agreed to postpone the professional game in England until 3 April at the earliest.
"This action, which will be kept under constant review, has been taken due to the increasing numbers of Clubs taking steps to isolate their players and staff because of the COVID-19 virus.
"The postponements include all matches in the Championship, League One and League Two, as well as all Academy and youth team fixtures.
"In addition, clubs are being advised to suspend indefinitely all non-essential activities which include, but are not limited to, player appearances, training ground visits and fan meetings.
"Whilst the EFL Board has continued to take the advice and guidance offered by the Government and its health advisors, emerging developments mean now is the time to implement football’s contingency plans in response to the crisis.
"A further update on these plans will be given post an EFL Board Meeting next week.
"This decision has not been taken lightly, but the EFL must prioritise the health and well-being of players, staff and supporters while also acknowledging the Government’s national efforts in tackling this outbreak."
All Premier League matches have been postponed until 3 April at the earliest because of the coronavirus.
That means all professional football in England is off.
The decision to postpone matches until 3 April was unanimously approved by the EFL.
Matches in the Championship, League One and League Two have been called off until 3 April.
Organisers of the Paris-Nice bike race have announced the final stage on Sunday will not go ahead because of coronavirus.
The race will end after Saturday's stage.
The British Basketball League all scheduled games this weekend will be taking place as planned.
"We encourage all fans who are planning to attend games to follow the optimum hygiene practices as directed by the NHS including regularly washing your hands for at least 20 seconds with soap and water and to self-isolate should you experience any symptoms," a BBL said.
"As this is a rapidly moving situation, we are in constant contact with all BBL clubs and are closely monitoring the situation.
"Should anything change, we will act accordingly and inform all affected parties at the earliest opportunity."
We're expecting the decision from that meeting very soon, possibly around 11:00 GMT.

Although Chelsea’s game at Aston Villa on Saturday looks in serious doubt following Callum Hudson-Odoi’s positive coronavirus test, any decision of a potential postponement will be made at the Premier League’s emergency meeting this morning.
Clubs cannot decide to suspend a game on their own.

Brian Caldwell, Shrewsbury Town chief executive, on the financial impact of postponements or cancellations: "We’ve got five home games left, you are probably looking at £200,000-£250,000 would be lost by not having the income from not just tickets but bars, hospitality, programming income and everything else that we at this level all rely on.
“It could have a devastating effect on some clubs potentially having that loss of income.”

No one has got coronavirus – no one is ill but it is simply to get the players back into the country so they can look after their loved ones.
The tour has to be rescheduled and ideally before the summer of 2021 but for now, fans won’t be watching a series between Sri Lanka and England for a while.
If you want me to guess, then possibly January next year because England tour India late January into February and March, so they could use this Test series as a warm-up for that.
Following the announcement from Uefa that next week's Champions League and Europa League matches will not go ahead, these are the Champions League matches that will not take place:
Manchester United, Wolves and Rangers' Europa League matches have also been postponed.
We're expecting official confirmation from the Premier League and EFL shortly.

At this time, the physical and mental wellbeing of our players and support teams is paramount. We will now look to bring them home to their families as soon as possible. These are completely unprecedented times, and decisions like this go beyond cricket.
We would like to thank our colleagues at Sri Lanka Cricket for their outstanding support and assistance throughout this situation. We look forward to returning to Sri Lanka in the very near future to fulfil this important Test series.
