The English Football League chairman Rick Parry revealed that the season can be completed in 56 days with matches will be played behind closed doors.
In a letter sent to all 71 EFL clubs, Parry said the EFL is hopeful the campaign can finish in the summer, but there is no indication when it might begin again.
All 24 sides in the Championship still had nine matches to play while some clubs in League One and League Two have 10 games left.
“The 56 days is based on teams playing twice a week followed by the play-offs, although Wembley might not be available for the finale so an alternative venue may be needed.
“How and when we return is clearly subject to change and any decisions will be taken in conjunction with the government and relevant health authorities.
“It is our working assumption at this stage that matches will be played behind closed doors when we eventually return and as part of our contingency planning we are absolutely mindful of the need to try and mitigate the cost of this to clubs as best we can.”
The letter also suggested the start of next season could be delayed.
“Looking more long-term, the EFL must remain mindful of the implications that the extension of this season may have on the commencement of the 2020-21 campaign, although we will ensure there is a suitable break between the two, so as to allow clubs and staff sufficient time to regroup and prepare accordingly.
“I think there will be a sigh of relief as and when we reach that point, and what is clear right now is that Covid-19 continues to present hugely challenging and uncertain times for everyone, and our thoughts are with all those directly affected by the pandemic.”
