Celtic defender Mark Wilson may not play again this season after undergoing knee surgery.
Wilson is unlikely to feature for Celtic again this season
Gordon Strachan told the Evening Times the player "needs a little bit of his cartilage taken off."
It's the latest in a series of injury problems for the former Dundee United full-back, who's only managed 16 games for Celtic this season.
Wilson last played on 18 March in the 1-0 defeat to Falkirk.
And he is certainly ruled out of Saturday's Scottish Cup semi-final with St Johnstone.
