Paceman Gus Atkinson Adds to England's Fitness Worries.
'Major setback' for the touring side after Atkinson goes off due to a hamstring issue.
Gus Atkinson increased England's injury problems when he left the ground early on day two of the Boxing Day Test in the Ashes series.
The right-arm seamer felt a problem in his hamstring post-delivery that he bowled during the morning session.
The touring camp reported the 27-year-old had experienced "tightness" and required time on the sidelines in order to be assessed "during the day".
The series decider in this Ashes battle in Sydney starts at the end of the week.
England have already lost strike bowlers one seamer to a knee injury and Jofra Archer because of a side injury during this series.
Matthew Fisher was brought into the squad as cover for Wood.
His form was underwhelming during the first two matches, claiming a mere a handful of scalps.
He was omitted from the previous Test, then recalled for the Boxing Day match in the playing XI.
Atkinson showed better form in Melbourne, taking two wickets during the host's first knock, then making 28 with the bat being one of only three teammates to get into double digits.
Post a single over in Australia's second innings, he came back on Saturday morning and removed Scott Boland taken by the wicketkeeper.
Yet, at the end of the fifth over, he bowled a slower ball to the batsman and immediately felt at his leg.
The English bowler was recalled for the Melbourne match having missed of the third.
