The NRL is looking at a radical overhaul of the game - with the idea to change to four quarters and extending to 100 minutes of game time.
According to the Daily Telegraph the NRL's rules and competition committee proposed the changes to NRL CEO Dave Smith last week.
The newspaper reports that initial discussions have been positive but any changes, if they are agreed, would be several years away.
The proposal reportedly would see four quarters of 25 minutes with five-minute breaks for each quarter and 10 minutes at halftime.
The interchange bench would increase from four players to eight, increasing the match-day squad to 21, to avoid adding more workload on the players.
