Abdul Fatawu's first half effort seemed to have been enough to grab the Foxes a tight win in which Wednesday were left nursing a familiar tale of woe - of missed chances and headache as to how their efforts could again go unrewarded. And more missed chances.
That was until Callum Paterson - excellent on the night - cushioned a header into Jeff Hendrick's path in injury time for the Newcastle United loanee to poke home calmly.
It's a point - but the feeling of the evening suggests it could mean a little more.
Here are our ratings from Hillsborough.
5. Akin Famewo - 7
Received what looked to be a harsh yellow card on 19 minutes for a tangle with Fatawu. Got forward with excitement, making more dribbles than anyone else and at one stage went all Maradona on us. | UGC / Steve Ellis
6. Callum Paterson - 8
Back in the side after his suspension, he harried and hurried and was involved in plenty. Was tucked in more than usual. Missed a golden chance on four minutes but recovered to offer a constant outlet.. and to put the assist for Hendrick's winner on a satin pillow. A big, cross ball of energy. | UGC / Steve Ellis
7. George Byers - 7
We saw the return of the snarling Byers snap-tackle. That was fun. Carried the ball nicely and took on a couple of shots. | Getty / UGC
8. Will Vaulks - 7
Swung-in free-kick to find Diaby on 12 minutes was simply lovely. Broke things up, though a couple went past him. Made a match-high four tackles. Plays with an anger, which is nice to watch. | UGC / Getty
