SANZAAR Chief Executive Brendan Morris commented: “This is a great decision for the Rugby Championship. SANZAAR’s four national unions agree and we believe that the integrity of international matches is very important and where possible , matches must be played 15 against 15”.
SANZAAR believes that a 20-minute red card is an important deterrent to deliberate acts of foul play, while also protecting the continuity of 15v15.
The rule officially states that if a player receives a red card, he can be replaced after 20 minutes by another player. The 20 minutes from when a player receives the red card until he can be replaced are measured as “playing time”. This follows the same time measurement that already exists for a player with a yellow card.
A player receives a yellow card and is penalized for 10 minutes. If the same player then returns to the field after serving his 10-minute suspension and subsequently receives a second yellow card, which is equivalent to an automatic red card. After another 20 minutes, the player with the red card can be replaced.
A player who has been tactically replaced may return to the field to replace a red carded player and if a team has unused replacements on the bench, they do not have to use them to replace the sent off player before using players who have already been tactically substituted.
