The on-loan Arsenal defender is currently sidelined after undergoing a hernia operation.
"Kyle is out running at the moment and looking really well," said McCoist.
"I would hope to have him back just after the international break. I'm looking forward to that headache.
"The injury was a setback but the big lad just wants to play games and it will be great to have him back."
The Gers can go ten points clear at the top of the SPL if they beat Hibernian at Ibrox on Saturday.
