A broken leg sustained in the first minutes of Saturday's Western Derby didn't stop one West Coast Eagles women's team player from playing out the game.

West Coast Eagles coach Martine Pearman said the 19-year-old and medical staff mistook the break for a corked leg, with Miller playing out the remainder of the game in the forward line and kicking two goals in the final quarter.

The injury is understood to be similar to the broken leg Fremantle Docker player Nat Fyfe sustained during the first quarter of his team's preliminary final loss to Hawthorn in 2015.
