Guinea midfielder Naby Keita down for a third time as he loses the ball to Wilfried Ndidi in a 50-50.

Maybe Ndidi's studs were up. Could easily have been a card actually on second viewing.

It's a good corner by Moses Simon, causes a moment of panic, but nobody can turn it into the net.

An early knock for Guinea's Issiaga Sylla, who needs treatment after blocking Moses Simon's cross for a corner.

Second half = under way.

The early games at the Africa Cup of Nations have often struggled to get going due to the intense heat. The late games have been a lot more fun, like Guinea’s 2-2 draw with Madagascar & Ghana’s 2-2 draw with Benin last night. It’s very tough for the players to ask them to perform in these extreme temperatures.

Diegwu Nwankwor: The battle between Ndidi and Keita is so fierce and I am absolutely loving it

Mickey Bricks: Odion Ighalo lives up to the tag of being the most selfish footballer I've ever seen

Goalless at the break.

Guinea captain Ibrahima Traore hits one high and wide to finish the first half.

One minute added on.

Naby Keita is up again, but needs to go off the pitch because he got treatment. In all truth, he was probably rushed back a bit for this tournament. Liverpool said he was out for the season.

Naby Keita is down injured again. This time a Kenneth Omeruo kick to the shin.

Both managers unhappy with some of the tackles flying in and the lack of response from the referee. The fourth official has the right idea though, he is standing miles away from both of their technical areas. Even Neil Warnock would struggle to shout at him from that distance.

Another ambitious Guinea shot but Ibrahima Cisse's long-range effort is easily saved. Their coach could do with telling them it's easier to score if you get into the other team's penalty area.

This is only 29-year-old Guinea keeper Ibrahim Kone's second cap. He used to be an Ivory Coast youth international before declaring for Guinea last year.

He was only on the bench for their opening draw with Madagascar but took Aly Keita's place today.

Guinea's defence back off Alex Iwobi and let him hit a bouncing shot towards goal which Ibrahim Kone, who plays in the French lower leagues, palms away.

Nigeria's third corner. But it's booted away.

This isn't good, Liverpool's Naby Keita is hobbling after getting a kicking from Peter Etebo of Stoke and Wilfried Ndidi of Leicester.

But the Guinea midfielder shakes it off. He was initially expected to miss this tournament through injury.
