Fourth substitute in extra-time permitted from first round onwards

This is the fa cup
The FA has announced that a fourth substitute will be permitted to be used in extra-time in matches from the first round onwards in this season’s Emirates FA Cup.
#2nd
Last season, The FA introduced the fourth substitute in extra-time from the quarter final stage of the competition, following a study from the International Football Association Board (IFAB) to analyse the impact an additional substitute in extra-time would have on a match and its outcome. In accordance with Emirates FA Cup competition rules, a maximum of seven substitutes may be nominated for a game, and a club may, at its discretion, use three of those seven substitute players at any time in a match during normal time.

This season, in the event that extra-time is played in any match in the competition proper, a club may use one additional player from the nominated seven substitutes during the period of extra-time. The Emirates FA Cup first round replays take place this week, with five ties scheduled between 14-16 November.
Have a nice day!
