Scotland manager Gordon Strachan sprang a major surprise in his first competitive squad by calling up Brighton midfielder Liam Bridcutt.
The 23-year-old Reading-born midfielder was joined by Dundee United winger Gary Mackay-Steven and Peterborough winger George Boyd in getting his first call-up ahead of the World Cup qualifiers against Wales and Serbia.
Boyd, who is currently on loan at Hull, previously featured for Scotland B in 2009 but had never made a full squad.

Gilks (Blackpool), Marshall (Cardiff), McGregor (Besiktas); Berra (Wolves), Caldwell (Wigan), Fox (Southampton), Hanley (Blackburn), Hutton (Real Mallorca), Martin (Norwich), Mulgrew (Celtic), Webster (Hearts); Adam (Stoke), Bridcutt (Brighton), Burke (Birmingham), Commons (Celtic), Dorrans (West Brom), Forrest (Celtic), Mackay-Steven (Dundee United), McArthur (Wigan), Morrison (West Brom), Snodgrass (Norwich); Boyd (Hull), Fletcher (Sunderland), McCormack (Leeds), Maloney (Wigan), Miller (Vancouver Whitecaps), Naismith (Everton), Rhodes (Blackburn).
