Australia's National Rugby League has announced a number of rule changes for the 2014 season.
They include a strong focus on stamping out time-wasting, as well as attempts to deter crusher and cannonball tackles
The changes include structured times when a captain can speak to a referee during a match and stopping the clock during the last five minutes of a game following a conversion or penalty shot at goal.
Crusher tackles will be graded at the higher end of charges, and referees have also been instructed to call "held" earlier when a player is trapped in an upright position, in order to prevent a third defender coming in late and making a cannonball tackle.
Under the captain's rule, a skipper can only talk to a referee during a stoppage in play and as players leave the field for the half-time break.
But penalties and scrums are not deemed to be considered breaks in play.
Under a new goal-kicking time limit, the referee will call time off at approximately one minute and 20 seconds following a try.
Fines will still apply to clubs when a player takes longer than one minute and 40 seconds to take a conversion.
