Premier League clubs remain committed to finishing the top-flight season but did not set a June 30 deadline to complete the fixture list at a meeting on Friday.
With the English top flight on ice since mid-March due to the coronavirus, it had been reported that as many as nine clubs were keen to complete the campaign by the end of June.
But it is understood that the 20 clubs did not discuss wrapping up the remaining 92 Premier League fixtures by then when they met on a conference call with league chiefs.
With fears that failure to finish the season could cost the Premier League more than £1 billion, clubs looked at various models for a potential return to action.
Britain is on lockdown until May 7 at the earliest to limit the spread of Covid-19, leaving English football to play a waiting game.
There is a general acceptance among clubs that matches will be played behind closed doors if the competition can resume, with restrictions on mass gatherings likely to remain in force for the foreseeable future.
A Premier League statement said a number of complex scenarios were being worked through.
"The health and wellbeing of players, coaches, managers, club staff and supporters are our priority and the league will only restart when medical guidance allows," it said.
"Today's shareholders' meeting provided an opportunity to discuss possible scheduling models. It remains our objective to complete the 2019/20 season but at this stage all dates are tentative while the impact of Covid-19 develops."
Premier League clubs are concerned by the legal implications of the campaign running past June 30, which is when standard player contracts expire.
FIFA, football's world governing body, has proposed that contracts be extended by mutual agreement until a club's season actually ends.
Premier League clubs are still holding discussions with players over wage deferrals and cuts.
Players were widely criticised for being slow to take pay cuts while clubs incurred the wrath of former players and fans by furloughing non-playing staff.
Liverpool, Tottenham and Bournemouth have since reversed their decisions to use the government's furlough scheme.
Southampton became the first club to strike a deferral agreement with their players last week and it has been reported that Arsenal are close to agreeing 12.5 percent salary cuts with their players.
Players are understood to be keen that any money deferred or cut from their wages goes to help the UK's National Health Service and charities during the pandemic.
"We are acutely aware of the distress Covid-19 is causing and our thoughts are with all those directly affected by the pandemic," the Premier League statement added.
