Fast bowler Gus Atkinson Compounds England's Injury Problems.
'Significant concern' for the touring side as Atkinson leaves the field suffering a hamstring problem.

The pace bowler pulled up with his left leg immediately following a delivery of the fourth over on Saturday.
Team management reported Atkinson reported "discomfort" and would spend time on the sidelines in order to be assessed "in the coming hours".
The series decider of the tour beginning on 4 January begins on Sunday, 4 January.
The English side has previously lost strike bowlers one seamer due to knee trouble and another paceman with an abdominal strain on the current trip.
Matthew Fisher was added to the party to provide backup.
Atkinson struggled in the opening two Tests, managing only three wickets.
He was omitted from the previous Test, only to be brought back for the Boxing Day match as Archer's replacement.
Atkinson showed better form in Melbourne, claiming a couple of wickets in Australia's first innings, before adding 28 while batting being one of only three England players to reach double figures.
Post a single over late on the first day, he returned the next day and removed Scott Boland edging to the keeper.
Unfortunately, at the end of the fifth over, he delivered a slower ball to the batsman and suddenly grabbed for his hamstring.
