Seamer Gus Atkinson Compounds the English team's Fitness Problems.
'Serious blow' for the touring side as Atkinson goes off suffering a hamstring problem.
Gus Atkinson further complicated the fitness woes of the England squad upon exiting the field on the second morning in the Melbourne Test versus the Australians.
Atkinson felt a problem in his left leg post-delivery in his spell during the morning session.
Team management reported the 27-year-old reported "discomfort" and would spend time away from the action for further assessment "in the coming hours".
The series decider of the tour in Sydney starts at the end of the week.
England have previously lost key quicks Mark Wood with a knee problem and Jofra Archer to a side strain on the current trip.
A replacement bowler was added to the party as injury reinforcement.
Atkinson struggled during the first two matches, taking just three wickets.
He was dropped of the third Test, then recalled for the Melbourne Test to fill the void.
Surrey's Atkinson performed better in the fourth Test, bagging two scalps in Australia's first innings, before adding 28 while batting being one of only three English batsmen to get into double digits.
After bowling one over late on the first day, he came back on Saturday morning and dismissed the nightwatchman taken by the wicketkeeper.
Yet, on the final ball of his spell, he bowled a change of pace to Travis Head and immediately felt his left hamstring.
Gus Atkinson was brought back for the Boxing Day Test having missed the Adelaide game.
