Miller struggling for Scotland
Kenny Miller remains a significant doubt for Scotland's Euro 2012 qualifier against Liechtenstein on Saturday but he is confident of facing Spain, assistant manager Peter Houston has revealed.
Miller suffered a groin injury which forced him off early in Cardiff's Championship clash with Hull on Saturday, but he is working with the Scotland physios and plans to travel with the squad when they fly out for the double header on Thursday.
He looks unlikely to be risked for the clash in Vaduz, with Brighton striker Craig Mackail-Smith set to step in, but the final group game in Alicante on Tuesday looks a realistic target.
Houston, speaking at the squad's base at Mar Hall in Renfrewshire, said: "Kenny Miller is still with us, he's progressing by the day. Kenny came up on Saturday evening and stayed here and the difference between Saturday and Sunday and him feeling better was quite amazing.
"It is going to be difficult perhaps for Saturday but certainly Kenny is more than hopeful and is still progressing. No-one knows their own body better than himself. He is working away with the physios and hasn't joined our sessions yet.
"Saturday might be difficult but certainly for Tuesday I have high hopes for him.''
Scotland only have three listed strikers in their squad, with David Goodwillie the back-up for Miller and Mackail-Smith, but the Cardiff striker's fitness doubt has not prompted another call-up.
"We haven't really spoken about bringing anyone else in with regards to that,'' Houston said. "I think it will be as you are with regards to the striker department if Kenny doesn't make it.''
Houston is confident Mackail-Smith can step in against Liechtenstein if required: "Craig Mackail-Smith is a bit similar to Kenny - he works very hard, is very, very quick and, more importantly he is scoring goals and in very, very good form.''
Houston confirmed Kilmarnock goalkeeper Cammy Bell had replaced Matt Gilks in the squad. The only other call-off was Gilks' Blackpool team-mate, Stephen Crainey, who was replaced by Lee Wallace on Sunday.
Aston Villa right-back Alan Hutton has been receiving treatment for a knee injury while Leeds winger Robert Snodgrass has an ankle problem but both are expected to be fit.
