Championship clubs are expected to release their retained lists this week.
With no permission to delay from the EFL just yet, clubs are said to be working to the original schedule.
Though, players whose contracts do expire on June 30 could yet find a way to extend to the end of the season, which will almost certainly be after that date.
So who are those players? And would any of these interest Cardiff City or Swansea City? Both teams have a lot of work to do on the recruitment front this summer, and finances are bound to be extremely tight.
We run you through the full list of free agents taken from Transfermarkt. We have included options on the contracts where known.
