Nicky Wroe's strike earned struggling Preston North End a point against Coventry but the hosts are now without a home League One win in 10 games.
Graham Cummins put Preston ahead with a close-range effort from Jeffrey Monakana's cross.
But Leon Clarke levelled when he chested the ball down and slotted in before the break.
Chris Robertson's own goal from Carl Baker's centre saw the Sky Blues go ahead but Wroe salvaged a point.
The draw means the Coventry are four points off the play-off, but have played two games more than Sheffield United, who are in sixth.
VIEW FROM THE DRESSING ROOM:
Coventry City manager Mark Robins told BBC Coventry and Warwickshire:
"I think we were wasteful, but I'm happy with the way we performed.
"I felt we'd done pretty well, and I bet that [goalkeeper] Joe Murphy's not had to do too much today. We were unlucky not to come away with what would have been a great win.
"They've got some good players, Preston, no doubt about that, so it's got to be a good point picked up towards our total.
"I'm pleased with the way we played, it's just that we could have done with another one going in the back of the net, or just with defending a little stronger."
