A warning from referees over high tackle technique will be trialled during Super Rugby World Rugby has announced, while other new laws will continue to be tested in lower forms of the game including a 50:22 kick.
The governing body of rugby has stated that player welfare is the sport's top priority.
Last year the World Rugby Executive Committee approved a package of innovative law trials specifically designed to reduce injuries at all levels.
One of those new law amendments, the high tackle technique warning, will be used in Super Rugby when the season kicks off on January 31.
The high tackle warning was successfully trialled at the World Rugby U20 Championship for the last two years and reduced the incidence of concussion by more than 50 per cent, World Rugby states.
