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.
9. Barry Bannan - 6
Like a few, fluid in his positioning. Skewed a shot wide in a monster moment 25 seconds in, one-on-one with time. Pressed with energy. Off with 12 to go as he tired a touch. | UGC / Steve Ellis
10. Marvin Johnson - 6
Inverted at times in what was a fascinating tactical viewing. A healthy pick-up on his last outing as he goes through the process of rebuilding match fitness. A couple were off-radar, but one fizzed cross was particularly eye-catching. | UGC / Steve Ellis
11. Bailey Cadamarteri - 7
Oh he's ever such a lot of fun. Asked to plough his efforts up against two full international centre-halves, he did well, earning Vestergaard a yellow card for some boisterousness on the half-hour. Had a shot blocked shortly afterwards. Generally exciting. Off for Musaba on the hour. | Steve Ellis / UGC
12. Liam Palmer - 7
On for his first minutes under the new manager, replacing Diaby in a reshuffle. Smashed Mavididi early on and used his body well on a couple of occasions. Shored things up on the right. | UGC / Steve Ellis
