"5 changes" - World Rugby set to confirm new laws for 2023 Rugby World Cup

The key changes are summarised in bullet points below: 

• The referee will put a stopwatch shot clock on kickers who will have 90 seconds to kick a conversion from the time a try is awarded, and 60 seconds for penalties, from the time the referee signals a shot at goal. 

• Match officials will expect lineouts and scrums to be formed within 30 seconds of the respective marks being set, and the ball to be used within 5 seconds of a ruck being formed.

• TMOs only ‘interrupt’ play to investigate serious, clear and obvious incidents of dangerous play missed by the Match Official team. 

• Referees can utilise the TMO to make a Yellow Card decision, but any extended TMO video reviews will take place once the player has left the field, not before the Yellow Card is issued.

• The TMO will have 8 minutes to either uphold a 10-minute Yellow Card decision or upgrade it to a 20-minute Red Card, in which case the player will not return to the field, but can still be replaced. 

• Referees will now also have the power to issue a full Red Card for deliberate foul play, in which case the player will not return to the field and cannot be replaced.
