Wigan midfielder James McArthur has been called into the Scotland squad for Wednesday's friendly against Slovenia.
His call-up comes after Celtic captain Scott Brown pulled out with a groin injury.
Meanwhile, Sunderland full-back Phil Bardsley and Blackpool winger Matt Phillips are both doubtful for the trip.
Phillips has arrived at the Scotland camp to have his hamstring injury assessed, the Scottish Football Association confirmed on their Twitter account.
Aylesbury-born Phillips, who qualifies for Scotland through his grandfather, had been expected to drop out after suffering a hamstring injury as Blackpool lost to West Ham in midweek.
The England Under-20 international, who has registered his change of allegiance with FIFA, missed his side's 3-1 win at Bristol City on Saturday.
Bardsley played 90 minutes as Sunderland lost 4-0 against West Brom on Saturday, but the SFA revealed he was doubtful with a calf injury.
