The sister of Collingwood star Travis Varcoe is fighting for her life after a freak accident on Sunday.

Margaret Varcoe was playing for Angle Vale in her suburban footy grand final when the sad incident occurred.

The 27-year-old was reportedly involved in an accidental on-field clash with a teammate and a member of the opposition, suffering a serious knock to the head in the process.

It is believed Margaret was able to walk from the ground to the change rooms, but her condition worsened rapidly after she suffered from a seizure.

She was then was then rushed to the Royal Adelaide Hospital for emergency surgery which she is yet to wake up from.

Messages of support for Margaret and the Varcoe family have been flowing in on social media.
