Fast bowler Gus Atkinson Adds to the English team's Injury Problems.
'Major setback' for the touring side as Atkinson is forced off suffering a hamstring problem.
The pace bowler further complicated the injury concerns plaguing England when he left the ground on the second morning of the fourth Ashes Test versus the Australians.
The pace bowler felt a problem in his left hamstring post-delivery that he bowled on Saturday.
The England team reported Atkinson had experienced "tightness" and required time on the sidelines for further assessment "during the day".
The final Test in this Ashes battle in Sydney begins at the end of the week.
The visitors have previously lost strike bowlers Mark Wood due to knee trouble and another paceman to a side strain on the current trip.
Matthew Fisher was brought into the squad as injury reinforcement.
The seamer had a tough time during the first two matches, managing only three wickets.
He was dropped for the Adelaide match, only to be brought back for the Boxing Day match in the playing XI.
Atkinson performed better in the fourth Test, claiming a couple of wickets with the ball, then making 28 with the bat being one of only three English batsmen who passed ten runs.
Post a single over late on the first day, he came back on Saturday morning and had nightwatchman Scott Boland caught behind.
However, at the end of that over, he delivered a change of pace to the batsman and promptly felt at his leg.
The English bowler returned to the side for the Melbourne match following his omission of the third.
