Back-row forward Wilkin started the first Test on the bench

Great Britain forward Jon Wilkin has rejected claims that Saturday's second Test will be an ill-tempered affair.

The New Zealand camp believe players could end up taking matters into their own hands because not enough is being done to stamp out head-high tackles.

But Wilkin dismisses those fears and says the players will be professional.

"All the things that happen off the field, I can say 100% do not have any effect upon the game and will not create any more conflict," he said.

New Zealand Rugby League chairman Andrew Chalmers has criticised the Rugby Football League's disciplinary process after Lions duo Adrian Morley and Sam Burgess both escaped suspensions for illegal challenges.

We are not just beating our chests, we have real issues and problems Andrew Chalmers NZRL chairman

Morley avoided a ban for a tackle on Awen Guttenbeil during the game between the Northern Union and the All Golds while Burgess escaped censure for his challenge on Fuifui Moimoi during Great Britain's victory in the first Test.

Chalmers told BBC Sport it was time to give players more protection before one of them got seriously injured.

"The system needs to be overhauled," he said.

"We have got a World Cup coming up in 2008 and we want things like independence, neutrality and some real consistency in place to protect the integrity of an event like that.

"We are not just beating our chests, we have real issues and problems. My concern is these athletes - they are million-dollar investments - are going to get hurt."

Chalmers said he intended to raise his concerns at a meeting of the International Rugby League Federation in November, but he made it clear he felt action was needed before then.

One of the things that probably sets rugby league apart from other sports is the amount of aggression that is allowed within the laws of the game Jon Wilkin

"It sends the wrong signal to players where those types of tackles fail to make it to the judiciary," he said. "That is absolutely clear to me."

Asked if he felt players might be tempted to dish out their own justice on Saturday, he said: "How the players respond, well, we'll find out very soon."

But he said he expected the match to be a full-blooded affair, adding: "You wouldn't want to miss the start of the game and I'd buckle my seatbelt up at home."

Wilkin agreed it will be another fiercely-contested encounter.

"It'll be tough because players are competitive and want to win the game, it won't be tough because officials have been squabbling in the background," said the St Helens forward.

"One of the things that probably sets rugby league apart from other sports is the amount of aggression that is allowed within the laws of the game.

"I think it's good to watch. I don't know about anybody else but I quite enjoy being involved when it's like that, so I'm quite happy for it to be like that again this weekend."

The RFL has made it clear it disagrees strongly with Chalmers.

It has also made a complaint of its own, with chief executive Nigel Wood criticising the Kiwis for sending too many non-playing personnel onto the pitch during the first Test.

Chalmers feels Wood's grievance is a minor one.

"My response to him was I think we've got more important issues that are facing the game that we need to address and address quickly," he said.

"I think they are genuinely had an issue with it, but for me it's a minor thing. We've got more important things to focus on."
