Celtic manager Neil Lennon claims skipper Scott Brown is likely to be fit for only one of Scotland's two forthcoming World Cup qualifiers.
Brown was recalled into Craig Levein's squad for the games away to Wales and Belgium after missing the opening two home qualifiers against Serbia and Macedonia with an ongoing hip problem.
However, the former Hibernian midfielder had to take anti-inflammatories and have an injection to take part in Celtic's 3-2 Champions League win over Spartak Moscow in Russia on Tuesday night and is struggling to be ready for the visit of Hearts in the SPL on Sunday.
Parkhead boss Lennon said: "I have spoken to Craig and he knows what the situation is.
"He will go to Scotland and he will play but I don't know if he will be able to play the two games."
