We'll be back in an hour or so for the build-up to the last quarter-final, as Burkina Faso face Togo in a battle of the minnows. Kick off at 6.30pm. In the meanwhile, you can chat to me on Twitter @Reda_Eurosport, about Ivory Coast's serial choking, and Nigeria's return to the big time.
That's it! Ivory Coast are out and NIGERIA are in the semi finals! A shock of sorts, but not surprising if you know how the Ivorians constantly fail in the tournaments!
Free-kick Ivory Coast on the right, Yaya Toure to take! Aimed at Gradel, headed clear but back with Tiote who crosses but Drogba heads well over!
The free-kick is taken short, the ball taken to the corner, a throw for Nigeria and Emenike goes down feigning injury.
Nigeria take it into the corners, and win a free-kick. Smart play as Emenike drew a foul off Gradel.
Four minutes added time being played. Four minutes for Ivory Coast to salvage extra time.
Booking for Enyeama for time wasting as he prepares to take a free-kick.
NIGERIA SUB: Yobo comes on for Moses. Shoring it up at the back now.
Gradel swings in the corner, cleared as far as Tiene, who handles. Free-kick Nigeria.
Brilliant block by Mikel, chucking himself at the feet of Traore after the ball landed for the giant striker! Corner.
Eboue with a poor cross from the right wing that is into the arms of Enyeama.
IVORY COAST SUB: Romaric is replaced by Lacina Traore, who is a 6'8" Anzhi striker.
Flick-on by Toure, he gets it back, now Gervinho who crosses but Toure with a high boot and Nigeria have a free-kick.
Having had a free-kick on the edge of the box, Nigeria play it safe and have it all the way back with keeper Enyeama.
Bamba is booked for a foul on Brown. Time running out for Cote d'Ivoire.
Well, Nigeria lead 2-1 as we approach the latter stages. This will be a frantic last few minutes.
GOAL NIGERIA! MBA WITH A DEFLECTED EFFORT! He's not done much of note in these past few matches, a surprise selection, but a fine turn of pace buys some space and his shot flies up in the air off Bamba and flies in!
Sabri Lamouchi looks on with a quizzical face. The former France midfielder, who is of Tunisian descent, is in his first managerial role after a long playing career.
Gradel is getting a lot more joy than Kalou, he's a very direct winger and wins a corner. He puts in another far-post cross after a short routine but over the head of Toure.
Gradel with another cross from the left, blocked by Oboabona. Throw.
Corner to Ivory Coast now as a Gradel cross hits Ambrose. Taken quickly but Enyeama grabs the cross and Nigeria counter. Emenike with a fine ball to Moses, but the flag is up - well offside.
Moses has been excellent with the dead ball so far but he overhits that corner out for a throw.
Moses on the move now, he finds Echiejele, whose shot-cross is blocked for a corner.
Tiene tries to get the cross in but Nigeria bring it clear...
IVORY COAST SUB: The disappointing Kalou is replaced by Gradel, who like him spent a long time in England before moving to France, although admittedly in the Championship and League One with Leicester, Bournemouth and Leeds.
Poor cross from Echiejele on the left, easy for Barry.
The Arsenal man was offside anyway it turns out so a goal-kick to Nigeria. The match has livened up.
GREAT DOUBLE SAVE ENYEAMA! Toure with the first effort after being sent in down the right. Great first touch to set up a fizzing low drive, Gervinho with the follow-up but again Enyeama parries.
Moses with an excellent delivery from the corner, Brown flying in at the far post, his header is into the ground and a scramble ensues with Barry clinging on to it! A fine save initially, and he has a free-kick. Bamba all over the place.
Brown shoots from range after trading passes with Moses, and Nigeria have a corner.
Nigeria on the move now as Brown plays it wide right to Moses. He takes on Tiene but overhits the cross.
A somewhat dreary spell now as neither side appears prepared to take the risks that could see a second conceded. Cagey is the word.
The corner is punched clear by Enyeama and Nigeria break. Emenike on the left finds Moses, who slows it down again. This was fine when they were leading, then Mikel sends a long ball over Ideye out for a goal kick.
Kalou sends Drogba in down the left but, as he searches an unmarked Gervinho, Ambrose blocks his cross. Corner.
Drogba takes a high one on the chest in typical fashion, but he runs it out under pressue from Oboabona.
Now Ivory Coast are hogging the ball. Nigeria need a change in my view.
Good pressure from Nigeria but look who's back defending on the edge of his own box - Drogba, who tackles Onazi and clears.
... And as Moses's ball comes in the ref blows for the pushing.
Moses to take this but there's a delay as the ref sorts out some pushing...
Corner to Nigeria as Echiejele puts in a cross from the left. They need to respond quickly, not been at the races this half.
The flag is up on Tiene after he is played in down the left - looked onside to me!
Gervinho runs it out on the left as Ivory Coast look to take this game by the scruff of its neck.
I have no idea what Nigeria were doing there - there was no marking, not man, not zonal, nothing. They were bunched around the near post having a cup of tea or something, Shocking.
GOAL IVORY COAST! Terrible marking by Nigeria as Tiote arrives unmarked at the far post to head Drogba's free-kick home. Awful defending.
Drogba skins Ambrose, great skill, and he wins a free-kick despite going down a bit theatrically.
Nigeria slow the tempo down now they are on the ball, stroking it around the back. And why not?
Free-kick Nigeria on the right, but Ivory Coast clear. Eboue on a mazy run, he feeds Kalou, who goes down in the area but is booked for diving!
The second half is underway, with Kalou and Drogba playing a one-two as Ivory Coast start promisingly.
Half-time and Nigeria deservedly lead 1-0 through that Emenike free-kick.
Romaric to take - and he curls the free-kick over the wall but it doesn't dip in time.
Eboue is tugged to the floor by Mikel so Ivory Coast have a free-kick on their right.
That was a stunning strike, the movement on the ball deceiving Barry. but it went straight through him though. Goalkeeping error, forced by the pace on the ball.
GOAL NIGERIA! Onazi touches the free-kick to Emenike, who blasts a ferocious strike past Barry! What a strike!!!
Romaric is spoken to after a foul on Emenike. All very scrappy now.
Drogba to take then - but it hits the wall and, as Enyeama dithers over claiming it, he is given a free-kick for a foul by Toure. Soft.
Another delay as Ivory Coast win a free-kick around 35 yards from goal, a touch to the left. Drogba territory now...
My mistake - the ref DID see that and he books Toure. It was just somewhat belated.
Worrying for Naija - Moses is down hurt. Toure with a sneaky arm out to prevent him running outside for the one-two, the ref missed it. Obviously.
Now they switch to attack but, after a promising move sees Toure slip it wide, Tiene overhits his cross from the left wing.
Ivory Coast have decided that they were lacking in possession so are knocking it about the back to get a feel for the ball.
Drogba is penalised for a handball as he turns in the box to fire in a shot, which Enyeama tipped wide anyway. Poor reffing as he took that on his chest, as clear as day.
Mikel quickly and cleverly takes a free-kick down the left but Moses is incorrectly flagged offside. These linesmen have been woeful at the Afcon.
Gervinho cuts in from the right and is tripped by Brown, who is operating as a defensive winger at the moment. Free-kick Ivory Coast, Drogba and Toure again discuss who will take it. No, Zokora replaces Drogba now... But Toure takes, cleared by Nigeria.
Zokora heads away Emenike's cross despite Barry leaping for it. Assume there was no call. Throw on the Nigeria right.
Toure to swing this free-kick from the left wing... Good ball in but nodded away. Gervinho keeps the ball in before finding Tiote, but his cross is deflected into the arms of Enyeama.
Kalou had swapped flanks with Gervinho to try and find some more space but all he's got was a whack round the ankles. On pitch treatment but I reckon he'll play on.
First booking goes to Onazi after he fouls Kalou on the Ivoria left. Clumsy, late and the Lille winger is hurt...
BAD MISS EMENIKE! Should have scored, Brown raced clear through the middle after Ivory Coast gave it away - Bamba and Zokora were backtracking and he slipped Emenike through on the right but he panicked and blasted it yards over. Had to score, just the keeper to beat and he was out of position.
Emenike just avoids straying offside but the pass from Mikel is too heavy. Goal kick Ivory Coast.
Drogba tries a shot and almost takes his pal Toure's head off. Toure questions the point of such an effort when he was directly in Drog's path. Tiote with yet another trip on Emenike. He'll surely be booked soon.
Corner Ivory Coast then but headed clear at the near post by Echiejele. Good intervention as Drogba was lurking.
Long-range effort from Tiote, which apparently took a deflection as it flew well over. Corner.
Moses with a training ground routine as he rolls it down the right but Emenike is sleeping and wasn't ready for it on the turn. He applauds the sentiment though.
Tiote fouls Emenike around 35 yards out. Moses and Mikel over it, with Brown and Oboabona the targets...
Nigeria play it around the back for a spell. Ivory Coast with a worrying lack of possession so far.
Oboabona fouls Kalou on the Ivorian right, but the ref decides it was a fair challenge. Seemed to block him off there!
Bit of a scrappy phase after what has been an entertaining opening to this match, fairly high quality too. Shame the stadium is 2/3 empty.
The replay shows that had someone risen properly in the six-yard box, Nigeria could have scored there. Brown as it was leapt the highest, but he was too deep.
Free-kick to Nigeria on the right, which Moses swings in but it's over everyone and out for a goal kick, despite the best efforts of Brown.
So a quarter-of-an-hour is played and Nigeria certainly shading it so far!
Moses pops up on the left, beating Eboue then brilliantly backheeling Emenike in, but Bamba closes him down and the Nigeria striker just bounces off the big man's frame. Lovely backheel from Moses though!
Romaric's corner is met by a Bamba bicycle kick, but they're not his speciality and he blasts it well over. Nice try though!
Kalou with a nice turn away from Echiejele, finding Drogba who is challenged by Oboabona, who concedes a corner.
All Nigeria at the moment as Emenike tries to get a shot away, closed down by Tiote.
Now Echiejele with a long-range effort but it's going well wide as Barry watches it pass.
Nigeria have been ranked as outsiders for this tie but with Moses in there you can never discount them - he fires a rasping long-range drive that Barry bats away!
Moses will take this free-kick, great ball into the six-yard box and Brown flies in but heads over!
Foul on Emenike on the Nigeria right, Tiote - who is wearing no.9 confusingly - with the clumsy shove.
Flag is up on Drogba after Romaric swings a lofted pass through - he was level too, poor decision!
The linesman signalled a goal-kick in the end, must have taken a touch off an Ivorian en route. Bamba is fouled while winning a header.
Looks like Drogba is going to shoot, it's a few yards to the right of the edge of the D... Nope, lefty Tiene took it with a surprise effort, little run up, off the wall and a corner.
A delay in taking this as Ivory Coast have a mothers meeting while Nigeria play games over the wall.
Drogba wins a free-kick off Echiejele, the Galatasaray striker backing into the defender and quite lucky to have got the decision.
The first half is underway!

If you want to get in touch with your pre-match predictions, feel free to Tweet me @Reda_Eurosport. Just to whet your appetite, William Hill have Ivory Coast as 4/11 favourites to go through, with Nigeria at 10/3 and definitely worth a punt in my view.
Nigeria boss Stephen Keshi has repeatedly shuffled his pack at these finals, sometimes bizarrely. There are only two changes today, which is conservative by Keshi's standards, as Brown Ideye comes back in for Ike Uche, whole Ogenyi Onazi replaces Fegor Ogude in midfield. Sunday MBa continues, despite failing to impress against Ethiopia. Victor Moses has been a revelation for Nigeria - as if we didn't already know how good he was - and he seems to be the main man now.
Ivory Coast fielded an experimental line-up for their dead rubber against Algeria, so the big guns return for this match. Indeed, the only players to remain are Didier Drogba, Romaric and Salomon Kalou, all of whom had been rested for at least one of the previous group matches. Talk about using your squad! Didier Zokora plays centre-back alongside Sol Bamba, with Kolo Toure apparently no longer trusted in that position.
