After a disappointing first day on Wednesday, England captain Michael Vaughan (left) must lift his dejected players on day two

After a delayed start, Andrew Flintoff has an lbw appeal in the first over, but only 15 balls are possible before the rain returns

After a 15-minute rain delay, the players return but England have trouble dislodging McKenzie and nightwatchman Paul Harris

McKenzie looks in good form as his second-wicket partnership with Harris passes the half-century mark

For a moment, England think they have McKenzie - but the third umpire rules the 'catch' had been grounded by Andrew Strauss

Nightwatchman Harris finally edges to third slip just before lunch, as South Africa reach 104-2 at the interval

Paul Collingwood is having a rotten Test match - normally England's best fielder, he drops Hashim Amla at second slip soon after lunch

But Amla lasts only one more over after being dropped, and he departs for nine as James Anderson takes a superb return catch

And Flintoff finally gets his man after trapping the dogged McKenzie lbw for 72 to leave the Proteas 135-4

All-rounder Jacques Kallis, who took 3-31 on Wednesday, leads South Africa's fightback in partnership with Ashwell Prince

Prince and Kallis's partnership reaches 70 by tea against a tiring England attack, as the Proteas reach 205-4, trailing by just 26

Rain extends the tea interval to an hour and a half, with Michael Vaughan's men battling to remove the increasingly confident Kallis

Flintoff is frustrated after he has a very good-looking lbw appeal against Kallis turned down by umpire Aleem Dar

But in Flintoff's next over, he yorks Kallis for 64, as his team-mates and the Edgbaston crowd go wild

Flintoff then picks up his fourth wicket of the innings when he has AB de Villiers caught at long leg by Ryan Sidebottom

When bad light finally curtails the day's play, South Africa are 256-6 - 25 runs ahead of England
