Schalke 04 defender Sead Kolasinac is likely to miss the next six months after picking up an anterior cruciate ligament tear in his knee.
The 21-year-old, who suffered the injury in yesterday's 2-1 defeat against Hannover, is expected to undergo surgery next week.
A statement on the Bundesliga outfit's official website confirmed the news earlier today.
Kolsasinac made 24 appearances for Schalke last season, and was rewarded with a place in Bosnia-Herzegovina's World Cup squad earlier this summer.
