Furious Shaun Wane has declared himself “offended, shocked and amazed” after Bulls counterpart Francis Cummins made an official complaint to the RFL over Wigan’s tackling techniques.

Cummins was angry with the Warriors’ tactics in both last Friday’s Super League clash and the Under-19s game the following day, which saw a mass brawl at the end of the game.

The Bulls boss suggested knee injuries to Matty Blythe and Adam Sidlow may have been the result of illegal tackles in Friday’s 26-20 defeat.

Yet Wane said: “I’m amazed he’s said that. A rugby league tackle is hitting the legs, the speed of the tackle makes it very hard to aim and I’ll tell you now, we don’t train bad practice.

“I’m really offended by those comments, it was (a case of) third man i, doing a proper rugby league tackle. We practice nothing illegal here.

“I could say a lot on this matter. I’ll choose not to – I’ll think about the game first. But I’m really shocked, and my players will be shocked.

“I’ll not accept this lying down. I don’t want to get tit-for-tat but I thought Franny would have said something to me after the game if he had a problem, and he never did. I’m amazed by this. And offended by it.

“I heard Franny’s press conference and he was saying, ‘you come here and you don’t get the calls’.

“When he watches the game back he’ll be embarrassed. Now he’s said this, he’ll be even more embarrassed.”
