North Melbourne looks set to retain star captain Andrew Swallow NORTH Melbourne remains confident star midfielder Andrew Swallow will be fit to face West Coast on Friday night despite injuring his knee on Saturday. The Roos could also retain young gun Aaron Mullett, who finished the win against the Western Bulldogs on crutches with an ankle complaint. And in a further boost, Brad Scott looks certain to welcome back defender Nathan Grima, who missed the Round 7 victory with soreness. The Barometer: Medical updates of every club Grima kept Justin Westhoff goalless in Round 6 and looms as a crucial inclusion against the Eagles' tall timber up forward including Jack Darling, Josh Kennedy and ruckmen Dean Cox and Nic Naitanui. There were early fears Swallow would be sidelined, but the Roos will place him on a modified training program this week in a bid to boost his recovery. He has very little swelling and a high level of function. Andrew is a very good chance to be cleared to be available to play this week," North's medical services manager Steve Saunders told the club's website. Andrew has presented very well today, he had his scan this afternoon and all the major ligaments look really good and sound. Swallow injured his right knee when Bulldog Liam Picken fell across him in an attempted smother in the last quarter. The Roos have enjoyed a golden run with injury this year, while Taylor Hine (ankle) will also be available for selection this week. The only blow is Robbie Tarrant, who is set to miss again with a leg injury.
