Aston Villa defender Alan Hutton is not expected to play again until at least mid-November after suffering an injury in training.
The full-back missed last Monday’s trip to Loftus Road and may even be absent when Scotland face England at Celtic Park on November 18.
He will definitely sit out Sunday's Premier League clash with Tottenham as well as West Ham six days later.
Villa boss Paul Lambert said: "The Scotland game will be touch and go. I know we've got a fortnight roughly to go but it depends how quick a healer he is.
"Alan sprained his ankle in training, on the Friday before the QPR game. There was no major tackle.
"Alan and Philippe (Senderos) were part of a back four who barely conceded a goal in the first four games."
The Scotland game will be touch and go
Hutton has impressed this season and signed a new three-year deal in September.
