It's all over. The ref brings an end to an exciting encounter. Both sides gave it their all and the scoreline shows it. Yet another draw in the 2013 Africa Cup of Nations.
Uche comes on to replace Ahmed Musa.
Eminike booked for an unknown reason just as his substitution is called off.
Kennedy Mweene steps up to the plate in a spectacular way. Sends Enyeama the wrong way and puts it in the top corner. 1-1.
Mayuka tugged down on the edge of the area by Onazi. Soft penalty to say the least.
Zambia beat the offside trap to go two-on-one, but are to slow to work it into the box, with Collins Mbesuma putting a disappointing shot on goal.
That's it for Victor Moses' AFCON debut. The Chelsea man is replaced by Brown Ideye.
Nwankwo Obiorah comes on for Nosa igiebor.
Emmanuel Mbola goes into the referees book for an unknown reason.
Jonas Sakuwaha comes on to replace Isaac Chansa
Another chance goes begging. Rainford Kalaba with a golden opportunity to get the equaliser, but he's unable to outsmart Enyeama, who easily clears the ball.
Ahmed Musa gets a booking for fouling Sunzu while going for the header.
Double change for Zambia as Chisamba Lungu comes off for Mukuka Mulenga, while Christopher Katongo is replaced by Collins Mbesuma.
Yellow for Nathan Sinkala after clattering Onazi in the midfield.
Zambia have it all to do in the group now if they want to progress to the knockout stages of the competition. However, I wouldn't write them off in this match just yet.
Lungu gets dispossessed by Mikel who puts through Emineke on goal, and the big number 9 makes no mistake in putting the ball past Mweene.
Nigeria have started the second half the brighter of the two, but both sides still look threatening on the break.
Nigeria break forward with pace, Musa does well to beat the defence, but the square ball is just too far ahead of Emineke to touch it in.
And we're back...
The referee brings the half to an end, not too much to report on, both sides look lively going into the break.
Zambia get a great chance to go one up, as Mayuka skins a few defenders on his way forward, but Chansa attempt to square the ball only finds Enyeama.
Fourth official confirms that there will only be one minute of stoppage time at the end of the half.
Still very evenly matched thus far, possession 50-50. You get the feeling that whoever scores first will probably go on to win the match.
Godfrey Oboabona gets booked for a heavy bodycheck on Christopher Katongo.
Lungu with a fantastic curling effort from the set-play, but Enyeama does well to push it round the post.
Mikel finds nothing but post with that penalty effort, looks like Mweene had it covered. Referee awards corner for some reason, which comes to nothing.
Davis Nkousa brings down Ahmed Musa just inside the box, no doubt in the referee's mind.
Victor Moses is having a good start to his Cup of Nations career, really giving the Zambian defence something to think about.
Lungu with a wonderful pass with the outside of his foot to find Kalaba free in the box, but he puts his first-time shot high and wide.
Mayuka looks lively for Chipolopolo so far, been involved all over the pitch, but it seems both sides are struggling in the final third.
Am Isaac from Nigeria, my prediction for today's game against Zambia is: ZAMBIA 1 : 2 NIGERIA - Isaac Aniefiok
The pitch at the Mbombela stadium looks in a terrible state, lots of sand kicking up. Neither team really in the ascendancy as yet, but Nigeria have been trying to find Musa down the left-hand side on several occasions.
Mayuka gets the ball on his head in the box between the two defenders, but he is unable to get the header down to test Enyeama.
Referee gets us underway for this titanic clash...

Some team news ahead for you ahead of the match...
Zambia are 12/5 to beat Nigeria today according to our friends at Sky Bet, while it is 21/10 for the spoils to be shared. Collins Mbesuma is 13/2 to score first, while Emmanuel Emenike is at 11/2.
Stephen Keshi's side also played out a 1-1 draw in their AFCON opener against Burkina Faso, who snatched a leveller deep into injury-time, while Nigeria finished the game with 10 men as Efe Ambrose was handed his marching orders in the 75th minute.
The Copper Bullets, 2012 champions, began this year's showpiece with a rocky 1-1 draw against Ethiopia, who hit back from 1-0 down even though they had played with 10 men since the 35th minute following goalkeeper Jemal Tassew's red card.
