Stokes number one keeper, ironically another Derby County loanee, Jack Butland fractured his ankle in March of last Year and is struggling to recover and has been told he will not be back before the start of next season.

Steve McClaren has already paid tribute to Grant and thanked him for all the service he has given Derby County
Grant played 186 times for Derby during his two spells with the club
