I was learning Laws of the Game from IFAB official website and have a question about the technical area.
In the Laws, it states as follows:
9. Technical Area
the occupants of the technical area:
- are identified before the start of the match in accordance with the competition rules
- must behave in a responsible manner
- must remain within its confines except in specific circumstances, e.g. physiotherapist/doctor entering the field of play, with the referee’s permission, to assess an injured player
Look at the third item in italic font. I don't see it clearly states about substitutes. I see substitution players do warm-up during the match, in the area along the touchlines outside of the technical one. Is anything mentioned about this clearly in other chapters?
