Norwich midfielder Korey Smith has been ruled out of the Championship clash with Leeds at Carrow Road.
The 19-year-old sustained an ankle injury from a heavy challenge by Reading's Jem Karacan at the end of last Saturday's controversial 3-3 draw at the Madejski Stadium.
Matthew Gill, who would have been a possible replacement, is also out with a calf injury which has left manager Paul Lambert short of options in midfield.
Defender Michael Nelson and midfielder Andrew Surman are not yet ready to return despite playing in a behind-closed-doors reserve game against Ipswich during the week while Adam Drury (calf) is still absent.
Lambert has revealed he has been looking to bring in a midfielder on loan in time for the game but admitted it was "more unlikely than likely to happen".
However, Lambert is boosted by the availability of captain Grant Holt after he had his red card at Reading rescinded at an FA hearing on Tuesday following an appeal.
The game is a 26,300 sell-out and will set a new all-seater record for the stadium and Lambert added: "The crowd will make the game. They'll come in their thousands and it's got the makings of a great game."
