Seamer Atkinson Adds to the English team's Fitness Problems.
'Serious blow' for the English camp after Atkinson leaves the field due to a hamstring issue.
The English seamer further complicated England's injury problems upon exiting the ground on the second morning of the fourth Ashes Test versus the Australians.
The pace bowler pulled up with his left hamstring after the final ball in his spell during the morning session.
The touring camp stated Atkinson felt some "soreness" and was to take time on the sidelines in order to be assessed "during the day".
The series decider of the tour at the SCG starts this coming Sunday.
The English side has been without fast bowlers one seamer with a knee problem and Jofra Archer because of a side injury during this series.
Matthew Fisher was added to the party to provide backup.
Atkinson struggled during the first two matches, claiming a mere a handful of scalps.
He was dropped of the third Test, only to be brought back for the fourth Test in the playing XI.
Surrey's Atkinson improved at the MCG, taking two wickets during the host's first knock, and scoring 28 runs with the bat among just a trio of English batsmen who passed ten runs.
Following a brief spell late on the first day, he resumed the next day and removed Scott Boland edging to the keeper.
Yet, towards the conclusion of his spell, he sent down a variation to Travis Head and promptly felt at his leg.
Gus Atkinson was brought back for the Melbourne match after being left out the Adelaide game.
