Paceman Gus Atkinson Compounds the English team's Fitness Problems.
'Significant concern' for England after Atkinson is forced off due to a hamstring issue.
The English seamer increased the injury concerns plaguing England upon exiting the ground early on day two of the fourth Ashes Test versus the Australians.
The pace bowler felt a problem in his left hamstring after the final ball that he bowled during the morning session.
The England team reported the 27-year-old had experienced "tightness" and required time off the field for further assessment "in the coming hours".
The series decider of the tour at the SCG gets underway this coming Sunday.
The visitors have already lost strike bowlers one seamer to a knee injury and another paceman with an abdominal strain on this Ashes tour.
Matthew Fisher was brought into the squad as cover for Wood.
The seamer had a tough time early in the series, taking just a handful of scalps.
He was left out for the Adelaide match, then recalled for the fourth Test as Archer's replacement.
Atkinson performed better in the fourth Test, taking two wickets with the ball, and scoring 28 runs as a batsman as one of just three English batsmen to get into double digits.
After bowling one over in Australia's second innings, he resumed on Saturday morning and removed Scott Boland edging to the keeper.
Unfortunately, towards the conclusion of his spell, he sent down a variation to the batsman and promptly felt at his leg.
The English bowler returned to the side for the fourth Ashes Test following his omission of the third.
