St Mirren have an unchanged squad against Aberdeen. Goalkeeper Graeme Smith (finger) is out for another 10 days while Aaron Mooy (back) is also on the sidelines. Hugh Murray is still fighting back from a knee injury while David Barron returns to training on Monday after injury. Aberdeen have been boosted by the news that Rory McArdle has recovered from a shoulder injury ahead of their game. Chris Clark is still a slight doubt with a knee problem but could also make the trip to Paisley. Teenager Ryan Jack is suspended for the clash after being sent off in last week's goalless draw against St Johnstone. St Mirren (from): Samson, van Zanten, Mair, McGregor, Tesselaar, Teale, Goodwin, McGowan, Thomson, Thompson, Hasselbaink, McLean, McShane, McHugh, McAusland, McKernon, Carey, McQuade. Aberdeen (from): Gonzalez, Foster, Considine, Mawene, Osbourne, Milsom, Pawlett, Arnason, Fyvie, Vernon, Magennis, Mackie, Low, Brown, Paton, Grimmer, Megginson, McArdle, Clark.
