Seamer Atkinson Adds to the English team's Fitness Worries.
'Major setback' for the English camp after Atkinson goes off suffering a hamstring problem.
Gus Atkinson further complicated the fitness woes of the England squad upon exiting the field early on day two of the Boxing Day Test against Australia.
Atkinson felt a problem in his hamstring post-delivery that he bowled during the morning session.
The touring camp indicated Atkinson had experienced "tightness" and was to take time on the sidelines to undergo evaluation "in the coming hours".
The concluding match of the tour in Sydney starts at the end of the week.
The visitors have been without strike bowlers Mark Wood with a knee problem and Jofra Archer with an abdominal strain on the current trip.
Matthew Fisher was added to the party to provide backup.
Atkinson struggled early in the series, claiming a mere a handful of scalps.
He was dropped from the previous Test, before being recalled for the Boxing Day match to fill the void.
The county bowler performed better in the fourth Test, bagging two scalps in Australia's first innings, then making 28 as a batsman being one of only three England players to get into double digits.
Following a brief spell late on the first day, he came back the next day and had nightwatchman Scott Boland caught behind.
Yet, at the end of the fifth over, he bowled a change of pace to Travis Head and immediately felt at his leg.
Gus Atkinson was brought back for the Boxing Day Test having missed of the third.
