Georgia Yeoman-Dale will have a mark on her forehead to remember the Wanderers loss to Perth Glory.
Early on in the match, Yeoman-Dale clashed heads with Glory defender Kim Carroll and saw a lengthy spell of medical attention for both players.
Both players attempted to go up for a header and fell to the ground with Yeoman-Dale having blood coming from her head.
The Wanderers forward was forced from the field for further treatment and later returned to the field sporting a white bandage cross her head.
While Carroll continued on in the match, she eventually succumbed to the head knock with blood coming from her mouth and was substituted at the 26th minute.
Speaking to the media after the match Glory coach Bobby Despotovski gave an update on Carroll's injury.
"Her mouth is swollen and has a couple of loose teeth but I think by Wednesday she needs to be free of concussion to play," he said.
"If she's not, she won't play next week."
Yeoman-Dale took to Instagram on Sunday night to share the extent of her injury.
The 24-year-old required 21 stitches to fix a gash in her head.
