Rhys Williams has been unable to convince Perth Glory coach Andy Keogh of his fitness for Sunday night's elimination final.
The Socceroo squad member has played just one full match in the last six weeks and starts on the bench at AAMI Park.
Luke Brattan is a surprising omission from Melbourne City's starting side, with coach Michael Valkanis opting for Osama Malik in midfield.
Ruon Tongyik comes into the side at Brattan's expense.
Captain Rostyn Griffiths is the inclusion for the Glory, with Mitch Oxborrow missing out.
