Rugby League International Federation (RLIF) chairman Colin Love has issued a warning about fiddling with the game's rules as a number of radical proposals gain currency in the NRL.

The Australasian competition already differs from the rest of the rugby league world in its use of two referees and the abolition of cornerposts as a part of the boundaries of the field of play.

Now NRL club bosses are considering further alterations such as playing games in quarters, giving coaches time-outs and even reducing matches to 60 minutes in order to maximise the return from the next television deal.

"I think the game needs to be careful about changing rules too readily without proper consideration," Love, also the chairman of the Australian Rugby League, told rugbyleague.com.

"If you look at soccer, they have made very few changes to their rules over the years and we can all see right now what a successful sport they have.

"The nature of rugby league is, aside from skill, a test of stamina as well and that is an element we don't want to lose.

"Also, if the game domestically becomes too far removed from what is played elsewhere, Australian players could be playing a different game when they take part in Tests and will have to adjust."

NRL club CEOs have been throwing up all sorts of suggestions for how the game can maximise its revenue when the new TV deal comes in in 2013.

At one end of the spectrum is Wests Tigers boss Stephen Humphreys' idea that each team plays each other team twice over 30 weeks while at the other end is a proposal from South Sydney's Shane Richardson that more derbies be built into a competition of only 20 or 22 weeks.

Interchange rules also differ between NRL domestic regulations and the international rules of the game.
