Paceman Atkinson Exacerbates the English team's Fitness Problems.
'Serious blow' for the touring side after Atkinson goes off suffering a hamstring problem.
The pace bowler added to England's injury problems after leaving the ground on the second morning in the Melbourne Test against Australia.
Atkinson pulled up with his left leg immediately following a delivery in his spell at the MCG.
Team management reported the 27-year-old felt some "soreness" and was to take time away from the action in order to be assessed "over the next few hours".
The concluding match in this Ashes battle at the SCG begins this coming Sunday.
The visitors have previously lost strike bowlers Mark Wood due to knee trouble and Jofra Archer to a side strain on the current trip.
Matthew Fisher was brought into the squad as injury reinforcement.
His form was underwhelming in the opening two Tests, claiming a mere a handful of scalps.
He was left out for the Adelaide match, 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 as one of just three English batsmen to get into double digits.
Following a brief spell at the end of day one, he resumed on Saturday morning and had nightwatchman taken by the wicketkeeper.
Yet, at the end of the fifth over, he sent down a change of pace to Travis Head and promptly felt for his hamstring.
Gus Atkinson returned to the side for the Boxing Day Test following his omission of the third.
