The Owls looked jaded and short on ideas going forward and were sloppy at the back.
With the playoff contenders elsewhere in good form, a second round of dropped points inside a few days feels like a knock, though they were helped as results elsewhere went their way.
Here are our player ratings on a difficult afternoon in Kent.
5. Sam Hutchinson - 5
Produced an important block early doors but looked a little shaky on the left. Moved into midfield late on and picked up a late yellow for backchat. Photo: Steve Ellis
6. Jack Hunt - 5
Worked hard on the right but got little joy on a frustrating afternoon. Rarely got the ball high up the pitch, where he has been so dangerous in recent weeks. Off for Mendez-Laing on the hour. Photo: Steve Ellis
7. Barry Bannan - 6
You can see what it means to him.. Did he try too hard in patches? Put in some good crosses, shot on sight and was the central threat on an afternoon Wednesday didn't have much. Photo: Steve Ellis
8. Massimo Luongo - 5
Battled hard but looked leggy, particularly in the first half. Stopped play cleverly one or twice. Sloppy on the ball. Photo: Steve Ellis
