Cooper welcomes sin-bin change

North Queensland Toyota Cowboys second-rower Gavin Cooper has backed the decision to allow NRL referees to be able use the sin-bin for instances of foul play.

The ARL Commission this week endorsed a recommendation from the NRL Competition Committee to allow referees the discretion to use the sin bin for serious instances of foul play – even if the victim is able to continue playing.

Cooper said he commended the decision, especially after the recent spate of late hits on Cowboys co-captain Johnathan Thurston.

"That's a part of the game that they have been trying to clear up for a while now. I know there has been a lot more of it made lately because the ones that have been made late have been really blatantly late," he said.

"If someone is willing to take the ball into the line then fair game, but after you've passed the ball and then take two steps that does turn into something that is very dangerous and pretty much a dog shot.

"As long as it refereed consistently across all games I'm sure it will be good for the game."

NRL CEO Todd Greenberg said the sin bin could be used for high tackles, dangerous throws, shoulder charges and crusher tackles.

"The sin bin could also be used for cheap late shots on playmakers who play such a key role in our game," he said.

"I stress that the sin bin will only be used for serious incidents and there will be no impact on tough, fair and legal play."
