NRL speaks on grapple tackle and

The National Rugby League has stepped in as an attempt to remove the dangerous and controversial grapple tackle through a set of guidelines to help referees police the dangerous tactic.

The core component is whether there's a second movement to make contact with the head or neck area involving a jerking, twisting or pinning action.

Also, the NRL has issued a strong reminder to clubs regarding the interchange rules. NRL chief operating officer Graham Annesley has indicated a number of minor incidents this year have been let through to the keeper. Last year Brisbane were handed a $75,000 fine after Corey Parker came onto the field for an injured Shane Webcke and proceeded to score a try against Wests Tigers.
