The English Rugby Football League is to trial the use of tap kicks instead of scrums as a way of restarting play after a 40-20 kick.
The system is currently used in the NRL and will be one of three experimental rules to be tried out in reserve-grade games in 2016.
In another change, if a team quickly forms a scrum to enable the referee to call time off, they must remain in the same positions when play resumes, which might remove the unusual sight of outside backs forming a front row if they are nearest to the referee.
The third experiment will see one forward in an attacking team being allowed to line up outside the scrum.
Meanwhile, the RFL has confirmed it will revert to having one video referee in televised games this year in an effort to speed up the decision-making process.
