Southampton midfielder Jordy Clasie has been ruled out of action for up to three weeks.
The summer signing from Feyenoord picked up a hamstring injury during the recent Europa League qualifying clash against Vitesse.
Although the complaint is not expected to keep the 24-year-old out for too long, manager Ronald Koeman admitted today that he could be sidelined until early September.
Koeman also revealed that centre-back Steven Caulker will miss this weekend's encounter against Everton because of a sinus infection.
