Darren Fletcher trained with the Scotland squad on Monday ahead of Thursday's vital Euro2016 qualifier with Poland.
The West Bromwich Albion captain suffered a knock on his side's 2-0 loss at Crystal Palace on Saturday but appears to have recovered and is likely to place in Gordon Strachan's line-up for the Group D fixture at Hamden Park.
Scotland currently sit fourth on the table as they chase a third-place finish which would see them progress to the play-offs for France 2016.
They are four points behind Republic of Ireland who will be chasing second-placed Poland when they host group leaders and reigning world champions Germany in Dublin on the same day.
