The NRL has confirmed the number of interchanges will be cut from 10 to eight and a shot clock for line dropouts and scrums will be introduced from next season.
The implementation of a referee bunker is also close to being rubber-stamped, with the proposal set to be put before the ARL Commission later in the year.
A decision has yet to be made on the length of the shot clock, with the governing body set to experiment with a time of 30-35 seconds in the under-20s competition in coming weeks, as well as dead-rubber NRL games towards the end of this season.
