Fremantle key defender Alex Williams’ season is over, after it was confirmed she tore her ACL in Saturday’s win over Geelong.

The injury means that the 25-year-old will be unavailable for Sunday’s crucial clash against the North Melbourne Tasmanian Kangaroos at Fremantle Oval.

With the likes of Jasmine Garner, Moana Hope, Kate Gillespie-Jones and potentially Emma King all likely to feature inside the forward 50 this weekend, the Dockers will need to find a suitable replacement to minimise the impact of the Roos’ well-oiled forward-line.
