Paceman Atkinson Adds to England's Injury Problems.
'Significant concern' for England after Atkinson goes off suffering a hamstring problem.
The English seamer added to England's injury problems upon exiting the ground on the second morning of the fourth Ashes Test versus the Australians.
The right-arm seamer experienced discomfort in his hamstring after the final ball that he bowled on Saturday.
The England team reported the 27-year-old felt some "soreness" and required time off the field in order to be assessed "in the coming hours".
The series decider of the series at the SCG starts on Sunday, 4 January.
The visitors have previously lost key quicks Mark Wood due to knee trouble and Jofra Archer to a side strain on the current trip.
Matthew Fisher was added to the party to provide backup.
The seamer had a tough time during the first two matches, claiming a mere three wickets.
He was omitted of the third Test, then recalled for the Melbourne Test to fill the void.
The county bowler performed better in the fourth Test, bagging two scalps during the host's first knock, before adding 28 while batting as one of just three England players who passed ten runs.
After bowling one over late on the first day, he resumed the next day and dismissed the nightwatchman taken by the wicketkeeper.
Yet, on the final ball of the fifth over, he delivered a variation to the batsman and promptly felt at his leg.
Gus Atkinson was recalled for the Boxing Day Test after being left out the previous Test.
