Richmond midfielder Kane Lambert has injured his ankle and is battling to be fit for the start of the finals, while Dan Butler has also had an injury setback.
Lambert underwent surgery on Monday after suffering a partial syndesmosis sprain in his ankle during Saturday's win over Gold Coast.
He will miss the next two games and is targeting a return in week one of the finals.
Butler had the same procedure and also hopes to return in the knockout stage.
