Cowboys aim to lure Newcastle's Korbin Sims north to join brothers Ashton and Tariq in Townsville Korbin Sims runs the ball for Newcastle. THE North Queensland Cowboys are determined to turn Townsville into Sims city. With older brothers Ashton and Tariq Sims on the club's NRL books, the Cowboys are in a battle with the Newcastle Knights to complete the trifecta by luring rising star Korbin north. While yet to table an offer, Cowboys football manager Peter Parr confirmed they had begun talks with Sims' manager Col Davis. "I don't think we're the only club outside of the Knights to speak to him," Parr said. So we've had some dialogue there, but where it ends up, I don't know at the moment. Having Tariq signed until the end of 2015 and Ashton (2014) could give the Cowboys an edge in the negotiation process, although the Knights, who have tabled a two-season offer, are understood to have more room to move in their salary cap. The 190cm, 112kg 21-year-old made his NRL debut against North Queensland in round three and has subsequently played six games. The Sims trio played together at the Brisbane Broncos between 2008 and 2010 although Korbin and Tariq were juniors and Ashton said he would love to be reunited once again. "I'd love him to come up, it would be good," he said. The last time the three of us were together was on the south coast back home. Ashton said he would do his best to help Parr in the negotiation process. Meanwhile, Parr said the Cowboys would not rule out Nathan Fien having a North Queensland swansong. The 34-year-old premiership winner with St George Illawarra is off contract and says he has no intentions of retiring at season's end. Fien, who started his NRL career at the Cowboys in 2000 before leaving at the end of 2004, said his preference was to remain a Dragon, but stated that a move back to where it started wouldn't be out of the question if there was interest. Parr said while it had not been discussed at the club, North Queensland had an open mind. "It might be something that we discuss in the future, but we've got some other priorities right now," he said. We like Fieny ... and given we have a lot of time for him and we know him, we wouldn't rule it out straight away.
