Fast bowler Gus Atkinson Adds to the English team's Injury Problems.
'Serious blow' for England as Atkinson is forced off due to a hamstring issue.
Gus Atkinson increased England's injury problems after leaving the playing area on the second morning of the fourth Ashes Test in the Ashes series.
The right-arm seamer pulled up with his left leg immediately following a delivery that he bowled during the morning session.
The touring camp stated the 27-year-old had experienced "tightness" and was to take time away from the action to undergo evaluation "during the day".
The series decider of the series at the SCG gets underway on Sunday, 4 January.
The visitors have already lost fast bowlers one seamer due to knee trouble and Jofra Archer to a side strain on the current trip.
Matthew Fisher was added to the party to provide backup.
Atkinson struggled in the opening two Tests, claiming a mere three wickets.
He was dropped from the previous Test, only to be brought back for the fourth Test as Archer's replacement.
The county bowler performed better in the fourth Test, claiming a couple of wickets with the ball, and scoring 28 runs as a batsman being one of only three teammates to get into double digits.
Following a brief spell late on the first day, he returned the next day and dismissed the nightwatchman edging to the keeper.
However, on the final ball of the fifth over, he delivered a slower ball to the batsman and promptly felt at his leg.
Atkinson was brought back for the fourth Ashes Test having missed the previous Test.
