Augustinsson has missed the season start with his German club team Werder Bremen due to a mysterious knee injury, which the team has found difficult to identify.

But now he has been operated on, and it is clear that he will be away from play for three months.

"Of course it's bitter for us," says coach Florian Kohfeldt on the club's website.

- But we will not whine and complain, it is only to accept the situation.

Thus, Augustinsson, who has recently been given left-back in the national team, misses the rest of the European Championship qualifier.

For Werder Bremen, the injury will be inconvenient, as the middle slopes Ömer Toprak is injured, and will be gone for about six weeks.
