Entering & Leaving the Field Without Permission
Players must have the referee's permission to enter or leave the field of play during a match. Doing so without permission is a cautionable offence.
The full rule
A player cannot enter or leave the field during play without the referee's permission. This applies to players returning from treatment for injury, players adjusting equipment, and substitutes entering. A player who deliberately leaves the field and re-enters to gain an advantage, such as running behind the goal line to appear onside, can be cautioned and their position for offside purposes is considered to be on the boundary line. If a player leaves the field and re-enters without permission and gains an advantage, they must be cautioned when the ball is next out of play.
