Seamer Gus Atkinson Compounds the English team's Injury Worries.
'Significant concern' for England after Atkinson goes off due to a hamstring issue.
The English seamer further complicated the injury concerns plaguing England after leaving the playing area during Saturday's play in the Melbourne Test in the Ashes series.
Atkinson felt a problem in his left hamstring post-delivery of the fourth over during the morning session.
Team management reported Atkinson had experienced "tightness" and would spend time off the field for further assessment "over the next few hours".
The final Test of the series beginning on 4 January begins at the end of the week.
The visitors have been without strike bowlers one seamer to a knee injury and another paceman to a side strain during this series.
A replacement bowler was added to the party as injury reinforcement.
Atkinson struggled early in the series, taking just three wickets.
He was dropped of the third Test, then recalled for the fourth Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, taking two wickets in Australia's first innings, then making 28 with the bat as one of just three England players to reach double figures.
After bowling one over at the end of day one, he returned for the second day's play and removed Scott Boland edging to the keeper.
Yet, at the end of his spell, he delivered a variation to the batsman and suddenly grabbed at his leg.
Gus Atkinson returned to the side for the Melbourne match after being left out of the third.
