Aberdeen have to make do without Hayes
Dons winger Jonny Hayes will be out for up to a month with a hamstring tear
Aberdeen winger Jonny Hayes faces three to four weeks on the sidelines after suffering a hamstring tear during Monday night's defeat to Inverness.
But Ryan Jack is available for Friday's Ladbrokes Premiership contest with Partick Thistle after recovering from a similar injury.
The Dons have no other injury problems to worry about.
Provisional squad: Brown, Logan, Shinnie, Taylor, Reynolds, Considine, McLean, Rooney, McGinn, Jack, Flood, Pawlett, Storie, Smith, Robson, Church, Wright, Harvie, McKenna, Ross, Collin.
