Fast bowler Gus Atkinson Adds to England's Injury Problems.
'Serious blow' for the English camp as Atkinson leaves the field due to a hamstring issue.
The English seamer added to England's injury problems upon exiting the field early on day two in the Melbourne Test against Australia.
Atkinson pulled up with his left hamstring after the final ball of the fourth over on Saturday.
The touring camp reported Atkinson had experienced "tightness" and required time away from the action for further assessment "over the next few hours".
The final Test in this Ashes battle beginning on 4 January starts at the end of the week.
The English side has already lost fast bowlers one seamer due to knee trouble and Jofra Archer because of a side injury on this Ashes tour.
Matthew Fisher was brought into the squad as cover for Wood.
His form was underwhelming during the first two matches, managing only a handful of scalps.
He was dropped of the third Test, before being recalled for the Melbourne Test in the playing XI.
Surrey's Atkinson performed better in the fourth Test, bagging two scalps during the host's first knock, and scoring 28 runs while batting among just a trio of England players to get into double digits.
After bowling one over in Australia's second innings, he came back the next day and removed Scott Boland edging to the keeper.
Yet, at the end of his spell, he delivered a change of pace to Travis Head and immediately felt at his leg.
Gus Atkinson was brought back for the fourth Ashes Test after being left out the previous Test.
