Paris Saint-Germain coach Laurent Blanc has revealed that Edinson Cavani is doubtful for Sunday's Ligue 1 clash against Lille at home.

The 26-year-old striker has been granted permission to return to Uruguay for personal reasons and the club are unsure when he will return to France.

Les Parisiens, who are also without the suspended Zlatan Ibrahimovic, are four points clear of Les Dogues at the top of the table.

"I can't say if he'll be back for the match on Sunday," Blanc told reporters.

Cavani has scored 12 goals in 17 league appearances this season.
