Full-time: Leicester City 2-4 Chelsea
- Cesc Fabregas scores two goals in as many extra-time minutes at the King Power Stadium to seal Chelsea's progress into round four of the EFL Cup
- The visitors, who kept ex-Foxes midfielder N'Golo Kante on the bench, initially defended terribly and trailed 2-0 courtesy of a brace from Shinji Okazaki
- Gary Cahill reduced the arrears with a header on the stroke of half-time and Cesar Azpilicueta levelled proceedings with an unstoppable volley
- Leicester were reduced to 10 men late on in normal time when Marcin Wasilewski collected a second yellow card for fouling substitute Diego Costa
- Antonio Conte's side bounce back from a disappointing defeat to Liverpool and overturned a 2-0 deficit to win for the first time in 14 years
That is all for this live blog, but be sure to check in with IBTimes UK sports editor Nick Howson tomorrow night as he brings you live coverage of the remaining eight EFL Cup third-round fixtures including Northampton vs Manchester United, Tottenham vs Gillingham and Swansea vs Manchester City.
He will also bring you the draw for the fourth round as it happens.
Goodbye for now.
So five-time winners Chelsea seal their place in round four after a thoroughly entertaining encounter. Conte will be pleased with the character and resilience shown by his side, but some of their defensive lapses in that first half will give the Italian cause for real concern.
They have the small matter of a Premier League trip to Arsenal on Saturday, while Leicester visit Manchester United. The Foxes also resume their Champions League campaign next week as Portuguese giants FC Porto travel to the East Midlands.
Leicester 2-4 Chelsea
Chalobah sends Fabregas clear with a well-weighted pass, but the Spaniard is rightly flagged for offside.
Ulloa goes down holding his calf after a robust aerial challenge from Cahill. Neither side has a substitution remaining and the striker will have to soldier on regardless.
Alonso's cross from the left is too pacey for Fabregas and his rogue touch sends the ball high and wide. Chelsea are cruising towards the finish line.
Luiz is the latest player to be carded for bringing down Vardy. Leicester are handed a free-kick in a dangerous position on the right-hand side but it is overhit and wasted by Drinkwater.
The second half of extra-time is upon us. Any comeback from Leicester now, considering their numerical disadvantage, would be truly miraculous.
It's at times like this that one really misses Golden or even Silver Goal. Fabregas' emphatic double has ended this as a contest but we still need to play the final 15 minutes.
Half-time in extra-time
Leicester 2-4 Chelsea
Evidently undeterred by fatigue, Moses races to the byline but his attempted cross lacks accuracy and is scooped up by a grateful Zieler.
Chilwell is then rightly cautioned for a reckless late sliding challenge on Azpilicueta.
Things probably should have gotten worse for The Foxes, but Costa fails to gamble in the six-yard box and Azpilicueta's perfect low cross is wasted.
Leicester look out on their feet now as Zieler has to get down low to tip a shot from Matic around the post. Hazard and Costa, as you might expect, have made all the difference for Chelsea.
An emphatic start to extra-time from Chelsea, who strike twice in quick succession to surely put this third-round tie beyond 10-man Leicester.
Fabregas has grabbed both goals, smashing in after a smart backheel from Hazard before firing home again after Leicester had failed to clear their lines.

The first period of extra-time is underway. Will this tie be settled in 30 minutes, or is a penalty shootout on the horizon?
We are heading for extra-time in the East Midlands.
End of 90 minutes
Leicester 2-2 Chelsea
Chelsea are going hell for leather in search of a winning goal. First Moses fizzes an excellent effort wide and now Costa bursts through before hitting the side netting.
Breathless stuff at the King Power.
Having just seen Hazard come on for Pedro, the last thing Leicester needed was to go down to 10 men with the prospect of an extra 30 minutes looming.
Wasilewski, who has looked miles off the pace tonight, picks up a second yellow card for a foolish challenge on Costa.
Gray makes way for Amartey. Four minutes of added time signalled.
Red card: Marcin Wasilewski (Leicester)
Almost a late chance for Leicester as Gray tricks his way towards the byline but rolls a low pass just too far behind Schlupp.
We are heading for extra-time, unless one of these sides can find a late winner. They are certainly both going for it.
Costa is becoming a real thorn in Leicester's side as the clock ticks down towards the end of 90 minutes.
After getting in between the centre-backs to fire a pass from Azpilicueta at Zieler, the fiery striker collects another Luiz long ball special and proceeds to bamboozle both Wasilewski and Chilwell.
His first drive is saved by the legs of Zieler, who gets back up to deny the follow-up shot from a tight angle.
