Many of the New Orleans Saints starters will not be on the field in Saturday's preseason opener. Head coach Kellen Moore said "mostly no" when asked on Wednesday whether his starters would play against the Jacksonville Jaguars. Moore hasn't completely finalized those decisions, however. He wants to evaluate the roster after Thursday's joint practice with Jacksonville before determining exactly who will be available.Yeah, well get through this joint practice, and then well kind of see where our numbers are, Moore said. But most of the starters are just going to get really good work in this joint practice, and then they wont play (on Saturday)."Thursday's practice with the Jaguars allows Moore and his staff to control how much work their starters receive while still allowing them to compete against another team. It also limits the injury risk that comes with playing them in an exhibition game two days later.Moore not officially declaring everybody out leaves open the possibility that a few starters could appear Saturday, depending on roster numbers and how the joint practice unfolds. Still, the game will largely serve as an evaluation opportunity for rookies, backups, and players who are on the bubble for the final spots on the Saints' 53-man roster.The Saints host the Jaguars at 3 p.m. CT on Saturday inside the Caesars Superdome. It will be the first of three preseason games for New Orleans, and their only exhibition game at home before road trips with the Los Angeles Rams and Dallas Cowboys.This article originally appeared on Saints Wire: Kellen Moore: Saints starters likely won't play in preseason opener
