Petronella Ekroth, 30, came to Hammarby closest from Milan at the end of July, and managed six matches before the injury occurred.
She states for the club's website that she is devastated and powerless not to be allowed to play football for a very long time.
- But I will really do everything to get back as fast as I can and I already long for that day!
This does not stop me, on the contrary, this will only make me even stronger, she says.
Petronella Ekroth has also represented Djurgården, Jitex and Tyresö in the Damallsvenskan.
