Loanee Leon Barnett is set to make his Coventry City debut tomorrow night against Derby County.
The centre half from West Brom is poised to play alongside Elliott Ward as Stephen Wright has still not recovered from flu and Ben Turner has a knee problem which has kept him out of training this week.
Also out is Keiren Westwood who has not recovered from a back problem and Dimi Konstantopolous will keep his place in goal with Danny Ireland on the bench.
