TODD Marshall will be replaced by Lindsay Thomas in the Power's Round 5 ANZAC clash with Geelong.
The late change comes after Marshall copped a concussion in Round 4 against Essendon, and fitness staff decided to risk the tall forward.
Former Kangaroo Lindsay Thomas will play his first game for the Power.
Houston, Wingard, Amon and Thomas will start on the bench for the clash.
