Adelaide Crows AFLW star Erin Phillips has suffered a serious knee injury during Sunday's Grand Final clash against Carlton.

The gun midfielder suffered the injury in the third quarter and was taken off the field on a stretcher to a standing ovation from the crowd at Adelaide Oval.

Phillips was in scintillating form in the decider prior to going down, recording 18 disposals, three marks, four tackles and booting two goals.

She firms as the favourite to take home best-on-ground honours with the Crows currently leading the Blues by 45 points at three-quarter time.
