Ferguson has been out of action for over five months with an ankle injury.
“It’s great to include Barry in the squad, but I don’t think he’s 100% fit yet,” Scotland boss George Burley said to the BBC.
“Rangers have two more games to play, so we’ll be looking at it carefully.”
Scotland squad:
Goalkeepers: Craig Gordon (Sunderland), David Marshall (Norwich City), Allan McGregor (Rangers).
Defenders: Graham Alexander (Burnley), Darren Barr (Falkirk), Christophe Berra (Hearts), Kirk Broadfoot (Rangers), Gary Caldwell (Celtic), Alan Hutton (Tottenham Hotspur), Stephen McManus (Celtic), Jamie McAllister (Bristol City), Gary Naysmith (Sheffield United).
Midfielders: Scott Brown (Celtic), Kris Commons (Derby County), Barry Ferguson (Rangers), Darren Fletcher (Manchester United), Paul Hartley (Celtic), Shaun Maloney (Celtic), James Morrison (West Bromwich Albion), Barry Robson (Celtic).
Forwards: David Clarkson (Motherwell), Kenny Miller (Rangers), Steven Fletcher (Hibernian), Chris Iwelumo (Wolverhampton Wanderers), Ross McCormack (Cardiff City), James McFadden (Birmingham City).
