With Westhoff unsuccessfully challenging a one-match suspension at the AFL Tribunal last night, John Butcher is a logical candidate to fill the void left by the versatile forward.
Butcher kicked three goals for Port Adelaide's SANFL side when it played two weeks ago.
Less certain is whether Jasper Pittard will play this weekend, with the running backman to be evaluated at training this week.
Pittard injured his foot against the Bombers last week and is rated a sixty percent chance to play on Saturday.
He could be replaced by any of the club's in-form SANFL players including Matt Thomas, Lewis Stevenson or Sam Colquhoun.
portadelaidefc.com.au will announce the Power's team at 5:55pm on Thursday night.

Cyril Rioli is expected to play his first full game after returning from a severe hamstring injury last week.
