The four Carabao Cup semi-finalists will be able to make five substitutions in their matches this week in a move that will please Manchester City boss Pep Guardiola.
City take on Manchester United in Wednesday's last-four League Cup clash with Jose Mourinho's Tottenham facing London neighbours Brentford in Tuesday's other tie.
As well as being able to make five in-game substitutions, the EFL also confirmed on Monday that teams are allowed to select nine players on their substitutes' bench.
As per the five substitution rules currently in place across certain parts of European football, the four clubs have just three opportunities to make substitutions excluding half-time, full-time and half-time in extra-time.
