There was also no starting place for striker Adam Idah, who has been away with the Republic of Ireland during the international break. He was named on the bench.
However, Wagner was able to name experienced striker Ashley Barnes, who hasn’t been seen since limping off during the home defeat by Leicester City two months ago.
Wagner also reverted to the tried and tested full-back pair of Jack Stacey and Dimi Giannoulis, having opted for Kellen Fisher and Przemyslaw Placheta for the last game, at Cardiff two weeks ago.
Shane Duffy returned from suspension to replace Jaden Warner at centre-back.
Marcelino Nunez was left out, having only been back since Friday after his Chile commitments, with Onel Hernandez returning.
City: Long, Stacey, Duffy, Batth, Giannoulis, McLean, Sara, Fassnacht, Barnes, Hernandez, Hwang. Subs: Reyes, Sainz, Gibbs, Idah, McCallum, Nunez, Fisher, Springett, Warner.
QPR: Begovic, Kakay, Dunne, Colback, Cook, Willock, Field, Dykes, Chair, Dixon-Bonner, Paal. Subs: Archer, Clarke-Salter, Dozzell, Richards, Larkeche, Kelman, Duke-McKenna, Drewe, Armstrong.
A well-taken first-half goal from Morgan Rogers proved enough to settle an entertaining encounter between two clubs with nothing but pride to play for.
It was a reward for a spirited showing from the visitors, who signed off on a positive note under caretaker head coach Stephen Dobbie, while for Norwich it was a sad exit for striker Teemu Pukki, who failed to mark his final game for the club with a goal.
