The Manchester City loanee is understood to have sustained an injury during the international break, and is replaced by Kellen Fisher in an inverted left-back role.
Jack Stacey fills in at right-back as a result, while Anis Ben Slimane replaces Emiliano Marcondes in midfield after coming on as a substitute in the 2-1 defeat to Bristol City 15 days ago. Marcelino Nunez, who has had a number of hamstring injuries to deal with this season, is kept on the bench.
Angus Gunn is back between the sticks after a hamstring injury meant Vicente Reyes and George Long deputising for him earlier this month, but Lucien Mahovo hasn't yet recovered from his knee issue.
The 19-year-old could be back with Johannes Hoff Thorup's group as early as next week, having last played in February's 4-2 win over Stoke.
Ben Chrisene (ankle) and Gabriel Forsyth (knee) are both out for the season, as Aston Villa loan export Lewis Dobbin. He's doing his rehab at Colney, as Thorup hopes to strike a deal to keep him in Norfolk next season.
Matej Jurasek, who also arrived in the winter window, is in the matchday squad after sustaining a thigh injury in his first start for Norwich.
West Brom top scorer Josh Maja will miss the end of the regular campaign and therefore this game, but could play again for the Baggies if they reach the Championship play-offs.
City are still hopeful of doing so themselves, although their chances are slim as they occupy 13th place in the table.
