Hammarby's ladies avoid playing their home match in the Champions League qualifier at BP's home ground Grimsta. The club writes on its website.
The opponent Benfica has agreed to change the match date, so Hammarby starts at home on September 18, which means the match can be played at Tele2 Arena, which is booked during the return round the week after.
The European Football Association (Uefa) has also approved the match change.
Hammarby's home ground in the women's top division is Kanalplan, which is not approved for European games.
