Versatile West Coast defender Mitch Brown has evaded a season-ending knee injury, with scans showing no damage to his right anterior cruciate ligament..

Brown has suffered bone damage to the knee as a result of a third quarter incident in the Carlton Draught Derby against Fremantle on Saturday and will be sidelined for the next four to six weeks.

It is still a significant injury, but that is much better than initially feared.

Also in that incident, when his leg was tucked under his body in an awkward manner, Brown hurt his right ankle and that injury will need a similar period of recuperation.

Brown again displayed his capacity to combat players of varying shapes and sizes as he opposed Fremantle livewire Hayden Ballantyne and did a good job of keeping the dangerous Docker under wraps.

The injury to Brown was the only medical concern coming out of the match as the team begins preparations for another top four contender, Sydney, at Patersons Stadium this Sunday.
