FIFA's proposed rule change that would enable Premier League clubs to make more than five substitutions in a match would also apply next season.
The temporary change needs IFAB approval before it can go ahead, but has been suggested to help players returning to action amid the coronavirus pandemic.
Teams will still only have three slots apiece, as well as the half-time interval, in which to complete the substitutions to avoid unnecessary stoppages.
It is hoped the temporary rule change will reduce the number of players - not match-fit and facing a congested fixture schedule - picking up injuries.
