Harry Bush, who hit his maiden century for Norfolk on Monday, will miss the second match of the county's Festival of Cricket at Manor Park, which starts on Sunday.
Norfolk face Cambridgeshire, but will be without the unavailable Bush, who made 100no in the draw against Staffordshire earlier this week.
His place could be taken by either Peter Lambert or Ali Shearer, although Norfolk have also named seamer Kieran Bunting in a 13-man squad.
A full match preview will appear in tomorrow's Pink Un.
Norfolk (from): JM Spelman, CJ Rogers, SS Arthurton, TR Ward, SK Gray (wk), LW Caswell, PA Lambert, AE Shearer, GW Walker (capt), C Brown, MW Warnes, MP Eccles, KJ Bunting.
