Lucas Joao missed Saturday’s home game with Hull City after suffering a groin injury in training.
Joao was in contention for a place in the starting line-up, as Atdhe Nuhu sat out the game through supsension.
However, Jos Luhukay said after the game that Joao had picked up the injury in training on Friday and so was ruled out of the Tigers clash.
Morgan Fox was substituted just before half time against Hull after suffering a back problem but Luhukay says he doesn’t think it is a serious injury.
