Jonathan Trott has not been considered for selection for Warwickshire's County Championship match with Worcestershire, starting at Edgbaston on Saturday.
Trott, 34, announced his international retirement earlier this week after struggling for form during England's drawn Test series with West Indies.
Opening alongside Alastair Cook, he scored just 72 runs in six innings.
"He [Trott] only arrived back in the country on Thursday morning," Bears boss Dougie Brown told BBC Sport.
"Obviously it's great to have him back and we're looking forward to seeing a lot of Trotty this summer but we still need to sort out exactly how we slot him back in. We just need the dust to settle first."
Trott had been considered as a possibility to play for Warwickshire this weekend when the England and Wales Cricket Board issued a list of players available for selection, but will now not feature.
The Bears have named the same 13-man squad on duty for the draw with defending county champions Yorkshire at Headingley.
Wicketkeeper Tim Ambrose is fit from the buttock muscle injury that forced him to miss that game, for which Peter McKay deputised.
The Division One meeting with newly-promoted Worcestershire is the first Championship game between the two neighbours since the Bears won the title at New Road in 2012, on the same day they effectively relegated their local rivals.
Warwickshire (from): Chopra (capt), Westwood, Porterfield, Ambrose, Evans, Hain, David, Barker, Clarke, Jones, Patel, Rankin, Wright.
