Last Saturday, Kastriot Imeri was forced to leave the field in the 37th minute in Young Boys' 2:2 draw with Lausanne.
Imer left the field injured.
The Swiss club announced on Tuesday that Imeri is expected to miss three to four weeks due to a left hamstring injury.
26-year-old Imeri returned to Young Boys after completing his loan at Swiss champions Thun.
He has scored one goal in the first three matches of the current edition of the Swiss Super League. But now he needs mandatory rest due to injury.
