England v Scotland preview
Ashley Young has withdrawn from the England squad for the international friendly with Scotland at Wembley on Wednesday night (KO 7:45pm).
The 28-year-old Manchester United winger has been suffering with an ankle problem and missed Sunday's Community Shield win over Wigan.
A Football Association statement said there had been discussions between England medical staff and their counterparts at Old Trafford and Young had returned to his club.
Michael Carrick has also withdrawn due to an eye infection. The 32-year-old midfielder had been in line to win his 30th cap at Wembley.
Liam Bridcutt, who made his one and only Scotland appearance against Serbia in March and is suffering from a groin problem, is the only absentee from Strachan's original pool of 29 players.
With another 13 midfielders at his disposal, Strachan has not added to his larger than usual squad.
A host of regulars return after missing June's victory in Croatia, including Celtic captain Brown and experienced striker Kenny Miller.
However, skipper Darren Fletcher, defender Gary Caldwell and striker Steven Fletcher remain sidelined for the Scots.
