The EFL have granted clubs to use five substitutions per match amid the hectic schedule caused by the coronavirus pandemic.
The move will put increasing pressure on the Premier League to perform a similar U-turn as the clamour grows for the rule to be reintroduced for health and safety reasons following a recent spate of injuries.
The five-sub rule will first be used in the EFL again when Coventry take on Birmingham in the Championship on Friday night at St Andrew's.
The five-substitute rule was introduced for Project Restart amid the coronavirus pandemic for player welfare but clubs voted to revert back to three changes ahead of the 2020-21 campaign.
