The UK Super League will copy the NRL by trialling two on-field referees throughout the 2019 season.
Super League has officially adopted a number of other NRL-first concepts, including golden point, an eight-man interchange, time off in the last five minutes when the ball is out of play and a shot clock for scrums and drop-outs.
But by far the most controversial adaption is the introduction of the dual referee system, which many NRL pundits believe has cruelled the natural flow of the game in Australia since its introduction in 2009.
There was a significant push for two referees in the Super League and ex-NRL players vouched for the move.
The Super League will look to make the dual referee system permanent for all fixtures in 2020 if trials proves successful.
The new rules will be in effect for February’s World Club Challenge match between the Sydney Roosters and Wigan Warriors in England, though it will likely be adjudicated by a lone referee.
While the NRL and Super League now share most of the same laws, it is not yet clear whether they will be carried over to the international game, which does not feature golden point, the shot clock or two on-field officials.
The Super League’s reasoning for the changes is to increase the time the ball is in play, with the NRL consulted on the matter.
