Mario Balotelli: Nice striker injures calf in training
Ligue 1 leaders Nice will be without Italian striker Mario Balotelli for at least the next three matches after he injured a calf in training.
Balotelli, 26, missed Thursday's 2-0 Europa League defeat by Schalke.
The former Liverpool player has scored six goals in six league games to help Nice to the top of the table.
"He will not be there for the next three games in the 10 coming days," said boss Lucien Favre. "For the games that will follow, we don't know yet."
Balotelli joined Nice from Liverpool on a free transfer at the end of August.
Team-mate Paul Baysse, who has been out for more than a month, will not play until the end of the year because of a knee problem.
Nice have 32 points from 13 games and lead second-placed Monaco and third-placed Paris St-Germain by three points.
