Jamie Vardy started the afternoon in fantastic fashion as he gave the Foxes the lead but Brendan Rodgers' men were pegged back just before half-time with a Teemu Pukki penalty. However a deflected effort from Marc Albrighton gave the East-Midland side all three points and leaves Norwich winless.
How it happened
Both teams headed into this fixture with their last league games resulting in heavy defeats so a shaky start was expected and that shown in the eighth minute as some sloppy defending by Manchester United loanee Brandon Williams allowed Ricardo Pereira to nip ahead of him and find Vardy with his clever pull-back.
The Foxes talisman found the top corner and celebrated infront of a sold-out away end at Carrow Road.
The Leicester fans happiness quickly changed to concern as Pereira pulled up with what looked like a Hamstring injury and was subbed off as the game was about to restart which is a real blow for the Rodgers as it adds to the already heavy injury list.
Just as Norwich were looking to head into the break a goal down, Turkish international Caglar Soyuncu slid in unnecessarily on French forward Pierre Lees-Melou which after a lengthy VAR decision, resulted in a penalty allowing Teemu Pukki to send Kasper Schmeichel the wrong way and equalise.
Leicester rode their luck at times in the second-half and were sloppy with their passing but sealed the victory thanks to clever build up play down the left from substitute Kelechi Iheanacho who fed James Maddison to set Vardy off his one of his lung-bursting runs.
The former England international found Marc Albrighton just inside the area before smashing a right-foot effort past Tim Krul albeit a deflection of Williams.
Albrighton was making his first league start of the season and as always, was an engine going forward and tracking back which is surprising that he only has 12 league goals.
Norwich thought they had hit back as Kenny McLean's header looked to seal the Canaries first point of the season however was ruled out for offside as Todd Cantwell was adjudged to be the last man.
Daniel Farke's side rallied late on and probably should of sealed a draw deep into stoppage time with substitute Adam Idah stabbing a close-range shot wide when he should of done better.
Death, taxes and of course another defensive injury
Rodgers' luck with injuries is proving to be torrid.
Jannik Vestergaard, Wesley Fofana, James Justin, Ryan Bertrand, Jonny Evans and Nampalys Mendy are all on the sidelines currently and now Pereira joins them on the treatment table just as the Portuguese international was looking back to his best.
The former Porto man pulled up just as the Foxes were about to restart after scoring in the eighth minute and quickly turned the jubilant Leicester fans cheers into concern as the last time he was injured he was out for almost a year.
His constant running and pressure was paying off this season setting up Vardy for both of his league goals this campaign and will be a huge miss should he be out longer than the international break.
A welcomed return was seeing Belgian star Timothy Castagne who was sporting a eye mask after his nasty facial injury during Euro 2020 and slotted in quite nicely at full-back and provided a constant threat overlapping Albrighton.
Anymore transfer business?
With deadline day looming, Leicester may see one or two outgoings in Dennis Praet and Hamza Choudhury but in terms of incomings they are after an attacking player and have been linked with Manchester United's Daniel James as well as Ademola Lookman from Red Bull Leipzig.
