Fast bowler Gus Atkinson Compounds England's Fitness Concerns.
'Major setback' for the touring side as Atkinson leaves the field due to a hamstring issue.
The English seamer increased the fitness woes of the England squad upon exiting the playing area early on day two of the fourth Ashes Test in the Ashes series.
The right-arm seamer pulled up with his left leg after the final ball that he bowled during the morning session.
The England team indicated the 27-year-old felt some "soreness" and would spend time off the field to undergo evaluation "over the next few hours".
The series decider of the series in Sydney gets underway this coming Sunday.
The English side has been without 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 early in the series, managing only three wickets.
He was dropped of the third Test, only to be brought back for the Boxing Day match in the playing XI.
Atkinson performed better in the fourth Test, taking two wickets with the ball, then making 28 with the bat being one of only three England players who passed ten runs.
Post a single over late on the first day, he resumed on Saturday morning and had nightwatchman edging to the keeper.
However, towards the conclusion of his spell, he sent down a change of pace to Travis Head and immediately felt at his leg.
The English bowler was brought back for the fourth Ashes Test having missed the Adelaide game.
