Monaco odds midfielder Camel Meriem could be out of action for six months after suffering a cruciate right knee ligament injury.

The 26-year-old, who has won three caps for France but was unlikely to be in the squad for this summer's World Cup, broke down during training on Thursday.

Should he require an operation, he will be sidelined until at least October.

"A decision regarding surgery will be made in the next few days," the club revealed in a press statement.

Meriem's loss would be a huge blow for Monaco, although they already look to be out of contention for a European spot next season.
