The date is subject to all safety requirements and government guidance being met and that clubs receive clearance from their local authorities to host games.
The season is scheduled to finish with a play-off final on July 30. Barnsley have nine games remaining and are bottom of the division, seven points from safety,
There will also be 20 players in matchday squads instead of 18. Teams can return to contact training later this week.
EFL Chair Rick Parry said: “With Sky Bet Championship clubs set to return to full contact training later this week and following Saturday’s government announcement, we are edging closer towards resuming the 2019/20 EFL season. “We have therefore today consulted with the Board’s Championship Directors and agreed to fixtures restarting behind closed doors on 20 June.
”Whilst matches will unfortunately have to take place without supporters, we are working with our broadcast partners, EFL Championship Clubs and all relevant stakeholders to broadcast the remaining 108 games plus Sky Bet Championship Play-Offs either live on Sky Sports, iFollow or a Club’s equivalent streaming service.
”We must stress that at this stage the date is only provisional and will only be confirmed once we have met all the requirements, as the health, safety and well-being of all participants, staff and supporters remains our top priority.
“Clearly completing the season in a safe manner is going to require a significant effort by all concerned and, whilst not unprecedented, it will need clubs to play a significant number of matches over a relatively short period of time.”
