The Owls were outdone by a hard-working Sky Blues side and so have made a poor start to their six-week run of schedule madness when it comes to survival hopes.
Take a look at our ratings from a poor outing for the Owls.
9. Andre Green - 5
Looked bright on the ball for large periods and his pace was a danger to Coventry, but he was sloppy in possession, never more so than in giving the ball away for Coventry's goal. Photo: Clive Brunskill
10. Barry Bannan - 6
Was central to every promising moment Wednesday had going forward. Was busy in an advanced role. Photo: Steve Ellis
11. Adam Reach - 5
What is these days a rare quiet performance. Wasn't quite at the races and wasn't able to produce the legs he usually offers. Photo: Steve Ellis
12. Josh Windass - 6
Worked as hard as anyone and together with Bannan offered an outlet. Could've done better once or twice but largely fed off scraps again. Photo: George Wood
