Monaco forward Stevan Jovetic has suffered a ruptured anterior cruciate ligament and will miss the rest of the season, the club have confirmed.
Jovetic was substituted in the 84th minute of Monaco's goalless draw against Reims on Saturday and is now set for an extended spell on the sidelines.
A club statement did not estimate when the player might return but confirmed that he would require surgery, bringing a premature end to his campaign.
Monaco coach Leonardo Jardim had speculated that Jovetic might have suffered an ACL tear following the match.
The 29-year-old has endured an injury-disrupted season due to calf, thigh and knee problems, scoring twice in just eight Ligue 1 appearances.
Montenegro international Jovetic only played 15 times in the league last term, netting eight goals after his reported €11million move from Inter.
