The English Football League (EFL) warned the economic crisis facing its clubs will not be spared by a resumption of matches behind closed doors as it delayed any return to training until May 25.
Unlike the top-tier Premier League, which is pressing ahead with plans to finish the season in a bid to satisfy lucrative television contracts, many of the 71 clubs in the three divisions of the EFL are far more reliant on gate receipts.
The UK government earlier this week paved the way for elite sport to return behind closed doors from June 1.
However, it is likely to be many months before supporters are allowed back into stadiums due to social distancing guidelines to help slow the spread of coronavirus.
"Solutions are still required to fill the financial hole left by the crisis," the EFL said in a statement after a meeting with clubs.
"The consequences of the COVID-19 pandemic will not be rectified simply by a return to play behind closed doors."
"However, until all outstanding matters are concluded, including finalising a comprehensive testing programme on matchdays and non-matchdays, the EFL Board has informed its Clubs that a return to training should not take place until 25 May at the earliest."
