Fast bowler Gus Atkinson Exacerbates the English team's Injury Problems.
'Major setback' for the touring side after Atkinson goes off suffering a hamstring problem.
The pace bowler added to the injury concerns plaguing England when he left the ground early on day two of the Boxing Day Test in the Ashes series.
The right-arm seamer pulled up with his left leg post-delivery that he bowled on Saturday.
Team management reported Atkinson had experienced "tightness" and would spend time away from the action to undergo evaluation "over the next few hours".
The series decider of the series at the SCG starts on Sunday, 4 January.
The English side has been without strike bowlers one seamer with a knee problem and another paceman because of a side injury during this series.
Matthew Fisher was brought into the squad as injury reinforcement.
Atkinson struggled early in the series, taking just a handful of scalps.
He was left out for the Adelaide match, only to be brought back for the Melbourne Test in the playing XI.
The county bowler improved at the MCG, claiming a couple of wickets with the ball, before adding 28 as a batsman among just a trio of English batsmen to reach double figures.
Post a single over at the end of day one, he resumed for the second day's play and had nightwatchman taken by the wicketkeeper.
However, at the end of the fifth over, he bowled a slower ball to Travis Head and immediately felt his left hamstring.
The English bowler returned to the side for the fourth Ashes Test having missed the previous Test.
