Uncapped Bouchier and Kemp in England Test squad
England have named an unchanged 13-man squad for the second Test against South Africa at Old Trafford, starting on Thursday.
Uncapped duo Ben Duckett and Matt Parkinson have been released back to their counties, while James Anderson remains out with an ankle injury.
All-rounder Sam Curran, who missed the first Test with a back injury, is fit to return.
Chris Woakes has been dropped from the squad, with Craig Overton keeping his place.
England are 1-0 down in the four-match series after losing the first Test at Lord's by an innings and 12 runs.
Squad
Joe Root (capt), James Anderson, Stuart Broad, Jos Buttler (wk), Sam Curran, Ben Foakes (wk), Jack Leach, Craig Overton, Ollie Pope, Ollie Robinson, Ben Stokes, Mark Wood
Analysis
The selection of Bouchier and Kemp is a sign that England are looking to add some extra firepower to their batting line-up.
Bouchier is a left-handed opener who has been in excellent form for Gloucestershire this season, scoring over 1,000 runs in the County Championship.
Kemp is a right-handed batsman who has also been in good form for Surrey, scoring over 700 runs in the County Championship.
The inclusion of Curran is a boost for England, as he is one of their most dangerous all-rounders.
Curran missed the first Test with a back injury, but he has recovered in time to be fit for the second Test.
The omission of Woakes is a surprise, as he has been one of England's most consistent bowlers in recent years.
However, Woakes has not been in great form this season, and he was expensive in the first Test.
Overton kept his place in the squad after taking three wickets in the first Test.
Overton is a tall, fast bowler who can also bat, and he will be hoping to make a big contribution in the second Test.
England will be looking to level the series in the second Test at Old Trafford.
South Africa will be confident of winning the series after their victory in the first Test, but England will be determined to bounce back and show that they are still the number one Test team in the world.
