English Football League clubs have been warned they face a "financial hole" even if games resume behind closed doors.
The EFL has been suspended since mid-March, but it was reported on Wednesday that the Championship could start up again in June.
That will be behind closed doors though, and the EFL board has warned that situation is not sustainable.
A statement said: "While there is much debate and discussion taking place publicly and privately regarding what should, or could, happen next, the EFL will continue to undertake consultation with our members before the next steps are determined.
"Current attention is clearly on the immediate next steps, but the long-term impact on the league and its clubs remains as stark as previously outlined, and solutions are still required to fill the financial hole left by the crisis.
"The consequences of the COVID-19 pandemic will not be rectified simply by a return to play behind closed doors."
That follows a similar warning from SPFL chief executive Neil Doncaster.
Scottish top flight clubs get more than 40 per cent of their revenue from gate receipts, so a lengthy ban on fans could have severe repercussions.
Doncaster said: "Unlike some leagues around Europe that are very heavily based around broadcast income, our club revenues are far more based on revenues that come directly from fans and that's largely through the turnstiles.
"We have made that clear to the Scottish Government. Broadcast income is very important but fundamentally, unless we start getting fans into our stadiums once again in the near future, then I do expect there to be extremely challenging times for all of our clubs."
