St Kilda has named its 26-man extended squad ahead of Sunday's match against Geelong at GMHBA Stadium.

Ryan Byrnes, Zak Jones, Arie Schoenmaker and Darcy Wilson have all been named to the extended squad after featuring for Sandringham in the VFL over the weekend.

The Saints will be forced to make at least one change to last week's side, with Dan Butler (elbow) making way.

The final team will be announced at 5:00pm AEST on Friday.

The game will be played at 1:10pm AEST on Sunday, and will be broadcast live on Fox Footy and Kayo.
