Leigh Griffiths is a doubt for Celtic's Ladbrokes Premiership game against Rangers at Parkhead on Saturday.
The Hoops striker had a scan on a hamstring injury which kept him out of Scotland's World Cup qualifying win over Malta on Sunday and is being monitored
Left-back Kieran Tierney, who also pulled out of Gordon Strachan's squad with an ankle injury, should be fit.
Provisional squad: De Vries, Lustig, Tierney, Sviatchenko, Ambrose, Toure, O'Connell, Brown, Bitton, Armstrong, Griffiths, Sinclair, Forrest, Roberts, Dembele, Ciftci, Izaguirre, Christie, Rogic, McGregor, Gordon, Gamboa.
