How do rolling substitutions work?

An unlimited number of substitutions may be made, at any time, whether the ball is in play or not, except during a timeout.

• The player coming off leaves through their own team's substitution zone and does not need the referees' permission.
• The substitute enters only after that player has left, also through their own team's substitution zone, and the referees do not need to authorise it.
• The substitution is complete when the substitute fully enters the pitch after handing the bib to the player being replaced.
• Permission can be refused in some cases, for example if the substitute's equipment is not in order.
• In official competitions a maximum of nine substitutes may be used; competition rules say how many can be named. The names of all players and substitutes must be given to the referees before the match.
