The sister of Collingwood star Travis Varcoe died in Royal Adelaide Hospital on Thursday, following a horrific on-field collision with a teammate in their grand final on Sunday.

The 27-year-old woman suffered a head injury in an accidental collision when playing for Angle Vale against North Adelaide in the South Australian Women’s Football League grand final.

She reportedly walked off the ground but collapsed in the changerooms, before being transported by ambulance to hospital.

She remained in a coma.

Channel 7 reported that the woman was surrounded by family, including Travis, when she died.

Tributes began to flow on social media shortly after the terrible news.

Terribly sad to hear the passing of Maggie Varcoe. It’s horrible to think she went to play a game of footy and never made it home. Thoughts are with her family and teammates.

Travis, 30, later sent a message through to Eddie McGuire on The AFL Footy Show on Thursday evening.

“[She] will love getting more air time tonight than her big brother,” he said.

As president of the Collingwood Football Club, McGuire passed on his well wishes to Travis and the Varcoe family during this difficult time.

“On behalf of the football world, and certainly all your friends at the Collingwood Football Club, we stand side by side with you and your family and everybody at the Angle Vale Football Club in Adelaide,” McGuire said.

“Our deepest sympathy, and we remember Margaret Varcoe tonight.”

Our thoughts are with the Varcoe Family at this time.#9AFLFootyShow pic.twitter.com/EWO6Ynp1np
