De Villiers gives Abbott the chance to redeem himself by throwing him the ball (gently, not hard in rage). Compton watches most of the deliveries sail by. A maiden.

Richard: Now we need to find an opening partner for Hales
Andy Mears: England should open with Compton and Root. Replace Cook with James Vince at 4 and Bell at 3
Harry O'haye: I can't help but think England are a better team with Compton opening and Bell at 3. No confidence in Hales.
Image source, AFPGoodness me, England nearly fritter a wicket away! Compton dabs to third man, calls for a risky second with Hales in cruise mode, and nearly collides with his partner on the way back. A better throw from Kyle Abbott and he would have been out, a fact AB de Villiers none too diplomatically acknowledges by hurling the ball into the ground in disgust.
Hang on, what's going on here? Dale Steyn, who was supposed to be on his way to hospital for a scan, has just trotted back on to the park! This injury saga has got more plot twists than the EastEnders Christmas special. Hales stonewalls Morkel.

"I have inside word from the England dressing room that Jimmy Anderson hopes to be fit for the next Test."
"Let it rip, Pietry!" yells AB de Villiers. He's got more variations than the spinner! Delicate from Compo, waiting on a slow off-break and tickling it down to third man for three.

Stuart Man Price: Gutted for Steyn. Better to face their strongest eleven and try for victory.
Tom Yardley: I hope Steyn comes back on. It's not the same without his threat.
There are suggestions that Dale Steyn has gone for a scan amid fears of a muscle tear. Remember there are only two days between the end of this Test and the start of the second. With the famously sedate Compton at the other end, Hales has got to take it on himself to inject a bit of impetus into this innings, which he does with a drive through the covers for two.

"I don't know a top six that I've ever played with that relish a third innings, even with runs in the bank."
"Come on Pietros," yells AB de Villiers behind the stump. It's more imaginative than 'Piedty', I'll give him that. Nick Compton blocks out his first four deliveries.

Image source, AFP"It's a two-card trick from Piedt. The previous ball spun. Cook got a long way forward, but it's good decision. It drifted in on the breeze and hit Cook halfway up the shin. Even though he got a good stride, you've got to think it would have hit halfway up the stumps."
Cook lbw b Piedt 7 (Eng 13-1)
Image source, APGot him, and what an excellent bit of bowling this is! Lovely flight from Piedt, it skids straight on through Cook's defences and raps him in front of the timbers. I was a bit dismissive of Piedt earlier, but he's now taken care of England's two best batsman in this match having dismissed Joe Root in the first innings - you can't argue with that.
I must say I'm not sure I agree with Dr Swann's diagnosis of Steyn's injury - he looked in a fair bit of pain to me. You may recall that during the morning session he had to fling himself to the ground to complete a tight single and it seems that may have exacerbated an existing niggle. Morkel switches ends and keeps Hales honest with a maiden.

Bertie: Tiny part of me happy Steyn is injured, but really wanted to see him at his best v England. Quality bowler and cricketer.
Image source, APDane Piedt into the attack to bowl some off-spin. He looks much more dangerous when he bowls a slightly fuller length, and he gets Alastair Cook shuffling back rather frantically with one that skids on. Tidy.

Amla realises what a huge player Dale Steyn is in this series and if there's a time you don't really need him it's probably now, 80 behind.
What a massive blow that is for South Africa, who are now down to two seamers. I'd bet good money we'll be seeing some dibbly-dobbly medium pace from Stiaan van Zyl at some stage today. Kyle Abbott completes the rest of the over pretty well.
Graeme Swann

"Dale Steyn is jogging off. He looks fairly fit. He went back to his mark as if he was going to carry on, until Hashim Amla told him to get off and see the physio."
