The Owls had their moments in the first half and responded excellently to Borja Sainz's first half opener but it was the home side that had the better of the chances. Bailey Cadamarteri's second senior goal was just reward for a purple patch of Owls pressure, before goals from Ashley Barnes and Jonathan Rowe took the points.
Barnes' match-turning effort came early in the second half and shortly after Danny Rohl had enacted a a system change for the second game in a row. Josh Windass and Michael Smith were not in the matchday squad.
Wednesday will hope to have them back available as they dust themselves down to go at a fellow resurgent relegation candidate in Queens Park Rangers at Hillsborough this weekend.
Here are our ratings from Carrow Road
9. Anthony Musaba - 6
A tidy carry offered a strong response from the Sainz goal and a minute or two later a good chance was struck over. Dangerous in moments but got the ire of teammates for giving the ball away in the build-up to Norwich's second. Made more tackles than anyone else on the pitch. | UGC / Steve Ellis
10. Bailey Cadamarteri - 6
Belted about causing carnage in the press in the first half. Took his second senior goal excellently, timing it well and showing fearlessness. Mouthful of blood for the trouble, too. Influence faded and he was taken off with 15 to go. | Steve Ellis / UGC
11. Callum Paterson - 6
Back in the starting line-up after missing out at Stoke through illness. Belted about and produced a vital block in first half injury time. A chance on his weaker foot on 51 minutes went a whisker wide - it was a decent chance despite the angle. | UGC / Steve Ellis
12. Marvin Johnson - 6
On at half-time for Byers as Wednesday shuffled things up. Offered an outlet, one cross in particular was dangerous, but like those around him couldn't sustain a killer punch. | UGC / Steve Ellis
