Etherington was taken off on a stretcher in the initial tie 11 days ago amid fears he had suffered serious knee ligament damage.
But following a rapid recovery the winger will now be assessed over the next 24 hours and may undergo a late fitness test ahead of the fifth-round replay at The Britannia.
Pulis is without Abdoulaye Faye and Andy Wilkinson through suspension, whilst Danny Higginbotham will have a fitness test after missing Saturday's 2-1 win at Portsmouth with a back spasm.
Stoke (from): Sorensen, Huth, Amdy Faye, Higginbotham, Collins, Lawrence, Sidibe, Whitehead, Delap, Diao, Kitson, Beattie, Fuller, Tuncay, Pugh, Whelan, Simonsen, Begovic, Etherington.
