FC Zürich's Tunisian midfielder Yassin Chikhaoui will miss the rest of the Swiss Super League season after an examination revealed he is suffering from a knee infection.

Although it has not been decided whether the 17-cap international requires surgery, the 21-year-old is expected to be on the sidelines for three months. Chikhaoui, who has scored eight times in 18 league appearances this term, last featured for Zürich on 2 March.
