Metcalf appeared an obvious inclusion for Saturday's clash but due to his contract turmoil won't make the trip to Kogarah, with Te Maire Martin wearing the No.7 jersey.
Martin played a starring role after replacing Boyd in the Warriors' big Magic Round win over Brisbane.
Prompted by Boyd's recent contract extension, Metcalf signed to join the Dragons from next year on a three-year deal, but hasn't played or trained while he sorted his future.
While overlooking him this week, coach Andrew Webster said he expected Metcalf to see out the season and be available for selection when he returned to full training.
