Kangaroos vetern Brent Harvey backs Jack Ziebell's playing style North Melbourne's Jack Ziebell on the ground after the bump on the Crows' Jarryd Lyons, as Rory Sloane steps in. NORTH Melbourne veteran Brent Harvey says teammate Jack Ziebell should not - and will not - change his playing style in the wake of yet another suspension. Harvey yesterday leapt to Ziebell's defence, saying his bump on Adelaide's Jarryd Lyons last weekend was instinctive. The Match Review Panel banned Ziebell, 22, for two weeks, but his penalty was inflated to three games by carryover points from suspensions incurred after bumps on Carlton's Aaron Joseph (four weeks) and St Kilda's Nick Riewoldt (three weeks) in the past two seasons. Telling Ziebell to take the bump out of his game, Harvey said, would change entirely the way he plays. "You can't tell somebody not to attack the football, because if you do that you're going away from the way (coach) Brad (Scott) has played," Harvey said. The ball was there and Jack plays on instinct, that's the only thing Jack can do. I honestly don't think Jack will change the way that he's playing and I don't think he can change the way that he's playing, because if you take that instinct away from any footballer, it's like telling Drew (Petrie) not to go for a mark. It's going to make it tough. We all see the way Jack attacks the football. He's going to give away a lot of free kicks. He goes twice as hard as anyone else in the competition. Harvey said North Melbourne had had to assess the risk and reward of challenging suspensions at the tribunal. Harvey, 35, will play his 350th game when North takes on St Kilda on Sunday, while Daniel Wells, 28, will play his 200th. "He (Ziebell) sent me a text message last night saying he was not so much sorry, but disappointed, that he wouldn't be there for Daniel and me and our milestones," Harvey said. That's just the type of bloke that he is. He's disappointed no doubt, but he'll come back. He's an animal - he trains really hard and he'll use these three weeks now to train hard, get fitter and make an impact. Harvey said losses to Adelaide (one point) and West Coast (via a Nic Naitanui goal after the siren) were as disappointing as any as he had experienced during his career. "As a leadership group we've got to take responsibility for that," he said. People speak about Brad all of the time, but the whole footy club has got to take ownership of it.
