NSW Country Origin prop Ben Cross has lifted the lid on rugby league's latest grappling controversy, claiming NRL clubs have been coaching the "chicken wing'' technique for at least three years.
In a revelation sure to add fuel to the grapple debate, Cross also claims that every NRL player would be trained to use the wrestling manoeuvre.
It was dubbed the "chicken wing'' tackle last week, but Cross said he was first coached in the technique at the Canberra Raiders in 2005.
Cross said he had since received the same coaching from wrestling gurus at the Melbourne Storm and Newcastle Knights.
The front-rower said NRL players were taught to pull a ball-carrier's free arm away from his body to stop him from propping himself up. It is designed to slow down the speed of the play-the-ball.
Cross also admitted it did have the potential to cause injury if players "take it a bit too far''.
Melbourne have again come under fire for being the instigators of the latest grappling move.
But Cross said it was under a wrestling coach at Canberra when Matt Elliott was in charge that he first experienced it.
"It's trained for at every club,'' Cross said.
"I remember when I was back at the Raiders in 2005 we used to practise it. It's not a new thing.
"We'd practise with the footy and (the wrestling coach) would show us how to stop guys from rolling on to their front to get a quick play-the-ball,'' Cross said.
"The standard move was to grab that prop-arm. It's been in the game for a while.
"Clubs have been doing it since I've been in the league since 2003 and I remember we practised it hard at the Raiders in 2005, just grabbing the arm that doesn't have the ball so players can't prop themselves on the ground.''
Cross said the motive behind the technique was not designed to injure the attacker.
"The idea is to hold (the arm) up, out or back in some way to stop the guy from using it to keep himself on his stomach or get himself up off the ground quicker.''
But asked if the tackle technique had the potential to get out of control, Cross said: "If blokes take it a bit too far or if the guy with the ball is fighting against the defender I guess it could get out of control.''
