Leicester striker Kelechi Iheanacho and Southampton midfielder Joe Aribo are brought on inside the first half of extra time.

It's Iheanacho's first involvement in the tournament after suffering a thigh injury before the competition. How fit is he? Will he be the Nigeria hero?

He's not played any football since coming in on as a second-half substitute for Leicester in their 1-1 draw at Ipswich Town on Boxing Day.

Victor Osimhen picks up the ball inside his own half and charges forwards, but he has no-one helping him and runs into bodies and South Africa clear.

Kuna: It's amazing how #VAR, external works

Dennis: Bafana Bafana lands another comeback while on the brink of elimination

Javel: SA deserve to lose this. Soooo many missed chances!

You have to love Emmanuel's confidence, but how will that disappointment of conceding a late equaliser affect the Nigeria players?

Well, who saw that coming?

Both teams gathered around the water coolers during the short break, desperately glugging down the fluids following that remarkable finish, with Nigeria in a tighter circle around Jose Peseiro while South Africa were more spread out and in a number of small clusters.

Yet another amazing finish to a game at this tournament and we go again for extra-time.

Afcon that.

South Africa were only a few minutes away from being eliminated, but are still in and still fighting, much to the delight of these fans back home.

Ivory Coast make four changes from the semi-final win over Mali, mostly down to a host of suspensions.

Serge Aurier, Odilon Kossounou and Christian Kouame are all banned, as is Oumar Diakite, who didn't start the last game.

Nicolas Pepe drops to the bench.

Sebastian Haller, Simon Adingra, Willy Boly and Wilfried Singo come into the team.

Ivory Coast XI: Y Fofana, Singo, Boly, Ndicka, Konan, Seri, S Fofana, Kessie, Adingra, Gradel, Haller.

We thought this would be the winning goal, but it wasn't. Watch William Troost-Ekong score the first of the two penalties we have had so far.

We could have a lot more penalties to come too.

To see a team go two goals ahead late on and then have the lead wiped out and brought back for an equaliser to their opponent is incredible.

Nigeria's players must have gone through such a rollercoaster of emotions in those minutes. I don't think that they have recovered since then.

Jose Peseiro is fun to watch at this tournament.

He has an enormous technical area to patrol here in Bouake so I would love to know what his step count is today.

The Super Eagles boss must know people are watching because he refuses to take off his smart jacket, even though it means he has to constantly mop the sweat from his brow with a towel.

After the quarter-final win a journalist asked if it was a lucky jacket.

Into extra time we go.

The most relieved man in the stadium will be Nwabili. How has he not pushed that free kick around the post?

And no one can believe that Mudau has not put the rebound in from yards out.

And South Africa so nearly win it in the sixth minute of added time.

Stanley Nwabali can only parry the ball and it falls straight to Khuliso Mudau.

All he has to do is hit the target from eight yards out and it is surely a winner.

But he blazes it over the bar! What a miss. That was for a place in the final.

South Africa are finishing like a train.

It is hard to believe that Nigeria are holding on until the final minutes of injury time here having led the game.

Nigeria are hanging on as South Africa have pushed forwards inside the six minutes of injury time. What a finish.

It's a great penalty from Teboho Mokoena.

Struck with venom, the goalkeeper gambles one way and the ball goes the other.

Just highlights the important save from Ronwen Williams minutes earlier. If Ademola Lookman scores it is game over. Now they are level!
