Celtic skipper Scott Brown looks set to miss Scotland's World Cup qualifier against Croatia.
The midfielder returned to action towards the end of the season, playing a big part in the William Hill Scottish Cup final win over Hibernian, after being troubled by a long-standing hip problem.
However, Brown appears to be struggling with his fitness again and he is unlikely to feature in Friday's clash in Zagreb.
Scotland boss Gordon Strachan told the Scottish Sun: "Scott has to call it a day for a while."
