Rule 8.1 of the competition’s guidelines says: “In all Competition Matches, each Club is permitted to name up to nine substitutes on the Team Sheet, of whom not more than five may take part in the Competition Match. Each Club is only permitted a maximum of three opportunities to make substitutions during the Competition Match. Clubs may make substitutions at half time and any substitutions made will not count towards the maximum of three opportunities. A Club may make more than one substitution at each of its three opportunities.”
