Stiller fell awkwardly on his ankle after a marking contest during the final quarter of Saturday's match against the Bombers and failed to take any further par in the match.
He was cleared on any major damage and will be hoping to recover by Saturday night.
News was also good for Michael Rischitelli who was cleared of any serious damage to an injured knee from last weekend's match. Rischitelli will also face a fitness test to determine whether he can play against the Pies.
Neither player has missed a match so far this season and will be determined to keep the streak alive.
