Tottenham Hotspur defender Radu Dragusin is set to miss the rest of the season after injuring the anterior cruciate ligament in his right knee.
The 23-year-old suffered the injury during Tottenham's defeat of Elfsborg in the Europa League last week and has to have surgery.
He is expected to be out for at least six months and some ACL injuries can keep players out of action for up to a year.
Tottenham said Dragusin "will be assessed by our medical team to determine when he can return to training".
Dragusin started 21 of Tottenham's past 23 games.
