Hawthorn could lose Liam Shiels after a bruising win over North Melbourne Sucker ... Lachie Hansen reacts after some Lance Franklin taunting. HAWTHORN young gun Liam Shiels will undergo scans on his troublesome ankle after being subbed out of Saturdays win over North Melbourne. The run-with player was on crutches after the game and he is not the only Hawk under an injury cloud with finals just around the corner. "Whenever a guy is subbed out of a game and can't return, you know that he is probably unlikely to play the next week," Hawks coach Alastair Clarkson said. Hawks hold off resilient Kangaroos Roughy has one hand on the Coleman We'll get it scanned - it's the same ankle that he hurt six or eight weeks ago and he's worked really hard to get back into it. We're hoping it might just be a little bit of a scar tissue and if so he might play next week. If not and the scans indicate he has done some damage there, he will miss a period of time. The Hawks will also closely monitor Cyril Rioli, who appeared to hurt his ankle late in the win. "I know he was limping for a time so that will get assessed by the docs, but I don't think it is too serious," Clarkson said. Injury ... Hawthorn midfielder Liam Shiels subbed out with an ankle injury. Jordan Lewis (hip) was a late withdrawal but will come in against the Sydney Swans next Friday night. Paul Puopolo has a slight calf complaint and should also return against the Swans. Buoyed by the security of a top two finish, Clarkson can afford to rest players next Friday night if he chooses. The Hawks coach said his side was "tracking okay" as the finals near. "We always knew it was going to be a tough game - we have a pretty high regard for how North have gone about it this year," he said. The game was played at a frenetic pace but quite often that is how the game is played at this stadium. We were down out at different stages through the second quarter and found a way to get back into the contest. It was pleasing to get that win and it obviously guarantees us a top two position, which have worked hard all season to try and achieve. Kangaroos defender Sam Wright distraught after the game. It was another frustrating day for the Kangaroos. They have now lost a record 10 games this season by 16 points or less. They were primed for the contest, but coach Brad Scott denied it had anything to do with the Essendon situation. "Contrary to popular belief we don't study the ladder," Scott said. I'm sick of reading about Essendon and I'm sure everyone is. I just focus on our team and what we have to do. The percentage motivation for what is happening at Essendon and potentially playing finals because of their misfortune was zero. Scott promised to throw everything at Collingwood in the final round next Sunday. "We will fight and bite and scratch for everything, because that's the North way," he said. We'll attack Collingwood with everything we have got and what will be, will be.
