The Sky Bet EFL has confirmed that it will temporarily increase the number of subistitutions allowed during games from three to five until the end of the 2020/21 season, as a move to combat fatigue and injury associated with the shortened off-season.
Championship Clubs will be able to name up to nine substitutes in their matchday squad, with five permitted to take to the pitch in any fixture, while League One and League Two Clubs can name up to seven substitutes in their squad, again with five permitted to take to the pitch.
The new rules will not apply to the Premier League, but may put pressure on the top tier to follow suite.
Premier League CEO Richard Masters told parliamentary inquiry last week he did not expect re-introduction of five subs "for the foreseeable future."
The change for the EFL will come in to place from Friday 20th November, and will run until the end of the season when it will be reviewed.
