Ian Burchnall says the lack of having seven substitutes has been responsible for Joel Taylor and Alex Lacey's absence from Notts County's squad.
Both players sat out Tuesday's draw with Halifax as the Magpies were held at home by the 10-man Shaymen despite dominating the game for 90 minutes.
Notts have made a tactical switch in recent weeks by moving from a back three to a four-man defence with Richard Brindley and Kyle Cameron first-choice centre-backs.
