Scotland's assistant manager Peter Houston has revealed that Kenny Miller is unlikely to face Liechtenstein this Saturday.

The Cardiff City striker is currently struggling with a groin injury which forced him off during the Bluebirds' loss at Hull City on Saturday afternoon.

However, Houston is hopeful that the 31-year-old will be fit to face world and European champions Spain next Tuesday.

"He is working away with the physios and hasn't joined our sessions yet," Houston told a press conference. "Saturday might be difficult but certainly for Tuesday I have high hopes for him."

Miller, who made his Scotland debut in 2001, has scored 15 goals for his country.
