North Melbourne spearhead Drew Petrie has signed on for another two years Drew Petrie has re-signed at North Melbourne. NORTH Melbourne forward Drew Petrie says he is clear on what actions are acceptable in a marking contest, despite the recent coaching and player backlash. The Herald Sun can reveal Petrie, 30, has agreed to a new two-year deal, tying the prized spearhead to the club until the end of 2015. Petrie, who was an unrestricted free agent, said he was thrilled to stay at Aegis Park to help steer the young Roos toward finals success. As a key forward, the veteran is at the coal face of the controversy surrounding perceived inconsistencies in recent marking contest rulings. But Petrie yesterday downplayed the furore, saying he understood that players would be penalised if they extended their arms in a pushing motion in a marking contest. "You just can't forcefully use your hands to push a bloke out of the way," Petrie told the Herald Sun. People do say that the test of strength has gone out the window a little bit because if you are too strong and you push a bloke away, you get a free kick against you, so I can see that argument. But I'm clear on what's expected. You can hold your position, definitely. But the extension of the arms and pushing a player away or in the back isn't allowed. Petrie, who last year booted a career-high 58 goals and finished fourth in the best and fairest, said he was thrilled to sign a multi-year deal, at his age. Kangaroos training at Aegis Oval Melbourne 8th May 2013, Kangaroo Drew Petrie has re-signed at the club. Picture: Petch Colleen Source: It is normal for 30-year-olds to sign one-year contracts but it is understood coach Brad Scott had a role to play in rewarding Petrie with an extra season. "The club has shown a lot of faith in me giving me two more years," Petrie said. But I feel I probably have shown them and deserve another couple of years to hopefully help take this side deep into September. The 228-game big man said he never considered leaving for more money. "There will be more movement of players in the coming years with free agency, which is great for players, but that's never entered my mind," he said. As long as the club was happy to do a deal then I was always happy to stay. Former captain Brent Harvey will return from a six-match suspension against the Western Bulldogs at Etihad Stadium on Saturday. Harvey was unwell earlier in the week but he said the tougher part was feeling helpless watching his team from the sidelines for the past six matches. "Obviously I do feel guilty because I should have been out there helping my teammates," Harvey said. But I think it was more frustration knowing how well we were playing but couldn't get the result on the board.
