Coventry City will be without Jack Cork and Leon Barnett for the FA Cup tie at Portsmouth tomorrow.
Neither Chelsea or West Bromwich Albion want their players cup-tied and with Patrick van Aanholt having been returned to Chelsea, this means changes for the Sky Blues.
Gary Madine, who has made nine substitute appearances for City is also not allowed to play after parent club Carlisle United refused permission.
"There will be two or three missing who have not got permission to play in the Cup by their clubs, but nevertheless we have still got a strong enough squad to go down and give a good account of ourselves," Chris Coleman said to the CT.
Portsmouth, who have Kanu, Hassan Yebda, Nadir Belhadj and Aruna Dindane on African Nations Cup duty, have been told by Tottenham that Jamie O'Hara willnot be allowed to play in the game.
