Rolling subs are to be permitted at Levels 5 and below this season.
It is not obligatory for Divisional Organising Committees to adopt
rolling subs in their areas but where they do, the key elements are
In a League Match, each team is permitted to use rolling
substitutions of not more than the maximum number of the player
interchanges set out below:
Number of Player
After Permitted Player Interchanges have been made no other replacements, substitutions or Player Interchanges are permitted for any reason, including injuries. If a player is injured the
team will play with one less player and with uncontested scrums if this involves a front row player and the game cannot continue safely with contested scrums.
Player Interchanges replace the blood bin. If a player has an open
wound and has to leave the field, and the team has used all of its
Player Interchanges, that player may not be replaced and the team
continues with a maximum of 14 players. The player is permitted to
return once the wound has been treated and the bleeding stopped,
subject to the 15 minute rule set out in IRB Law 3.10(a).
No more than two Player Interchanges per team may occur at
any one time and then only during a stoppage in play and with
the knowledge of the referee, who is entitled in his sole opinion
to refuse to allow or postpone a Player Interchange if he believes
either that the Player Interchange would prevent the opposition
from restarting the game quickly, or where a player has been
injured, or that it would not be safe for the replacement player who
has been previously injured to play in the match.
A player who is a replacement is not entitled to take a kick at goal until a passage of play has taken place since he has taken the field of play.
A player who suffers two injuries in a match necessitating his being
replaced on each occasion is not permitted to act as a replacement
following his second injury.
