World Rugby introduces mandatory multi-day rest for concussed players
World Rugby has further tightened up its concussion rules.
On 21 June, it announced that it would impose a 7 to 12 day period of absence for players who have left the field due to symptoms of concussion, effectively disqualifying them from participating in the next game.
This measure is one of many, as the official bodies have been aware for some years now of the risk created by too many concussions
The measure came into force on 1 July.
