Rugby League: Fake wobbles - Paul Gallen reveals NRL rort, says every club is involved

A moment in the Manly Sea Eagles and South Sydney Rabbitohs match has seen Cronulla Sharks skipper Paul Gallen reveal a tactic "every team does".

The HIA has aimed to test concussions in a bid to lessen the long-term effects of head and brain injuries on players.

However, Marty Taupau, who went off with what looked like a sore shoulder, was given the HIA test, which gave his side a free interchange.

"I've had an issue with the HIA forever and a day," Gallen said on Channel 9's Sunday Footy Show.

"In my opinion this isn't a HIA and if it is a HIA, he shouldn't be allowed back in the game because he stays down for an extended period of time. He has a neck problem here in my opinion. I'm not a doctor but I'm pretty sure it's a burner.

"He goes through a HIA, which is a free interchange, and gets to come back on the field which is another free interchange.

"We talk about this game becoming a war of attrition and limited interchange and referees aren't giving as many penalties these days, which I think is great, but if you're going to give away free interchanges through HIA it defeats that purpose."

NSW State of Origin coach Brad Fittler said it was becoming less common as the rule continues to evolve but Gallen said it's a widespread tactic across the league.

"I'm not picking on Manly because we all do it," Gallen said.

"All clubs do it and if you have an opportunity where there's a 50-50 call, the trainer makes them stand on one leg, they wobble a bit and they come off and get a free interchange."
