Nemanja Vidic is doubtful for
Serbia's World Cup qualifier against Faroe Islands on
Wednesday.
The Manchester United defender suffered an ankle injury in
Saturday's game against Austria and had to be replaced at
half-time.
It is not thought to be a serious problem but coach Radomir
Antic admits he is 'not very optimistic' about the centre-back's
availability for the midweek trip to Torshavn.
Nenad Milijas' penalty earned Serbia a 1-0 victory over Austria
and extended their lead at the top of Group 7 to five points.
France, Lithuania, and Romania are also battling to make it
through to next season's tournament in South Africa.
But Serbia are firmly in control and victory over Faroe Islands
would put them on the brink of qualification.
