SIX Saints have been named in a 25-man squad for Round 17 against Port Adelaide, with Alan Richardson's side set to bring two rucks to the party against the Power's Lobbe and Ryder combo.

ROUND 18: Ultimate game day guide for Power v Saints

Tom Hickey will play his first senior game for St Kilda since Round 10, and is set to start in the forward pocket, rotating with Billy Longer in the ruck.

It leaves two of either Cameron Shenton, Seb Ross, Nathan Wright, Tim Membrey or Daniel McKenzie to be named in the Saints' final team on Friday afternoon.

Nick Riewoldt, Jack Lonie and Sam Gilbert were forced out of Richardson's side to face the Power.

Port Adelaide has named Tom Jonas, Jasper Pittard and Sam Gray as three inclusions into its extended 25-man squad.

Both clubs will confirm final teams at 4:30pm on Friday.
