Paceman Gus Atkinson Adds to the English team's Fitness Problems.
'Major setback' for England as Atkinson leaves the field due to a hamstring issue.
The pace bowler added to the fitness woes of the England squad when he left the playing area on the second morning of the fourth Ashes Test in the Ashes series.
Atkinson pulled up with his left leg immediately following a delivery of the fourth over at the MCG.
Team management indicated Atkinson had experienced "tightness" and required time on the sidelines for further assessment "over the next few hours".
The final Test of the tour at the SCG starts at the end of the week.
The visitors have been without strike bowlers Mark Wood to a knee injury and another paceman to a side strain on this Ashes tour.
Matthew Fisher was brought into the squad as injury reinforcement.
The seamer had a tough time in the opening two Tests, managing only three wickets.
He was dropped of the third Test, then recalled for the Melbourne Test in the playing XI.
The county bowler performed better in the fourth Test, claiming a couple of wickets with the ball, before adding 28 with the bat as one of just three English batsmen to get into double digits.
After bowling one over at the end of day one, he resumed for the second day's play and removed Scott Boland edging to the keeper.
However, towards the conclusion of his spell, he bowled a change of pace to the batsman and suddenly grabbed his left hamstring.
The English bowler returned to the side for the Boxing Day Test having missed the previous Test.
