Seamer Atkinson Compounds England's Fitness Worries.
'Significant concern' for the English camp after Atkinson leaves the field with a hamstring injury.
The pace bowler added to England's injury problems after leaving the ground early on day two in the Melbourne Test against Australia.
The right-arm seamer pulled up with his left leg post-delivery of the fourth over on Saturday.
The touring camp indicated the 27-year-old reported "discomfort" and would spend time off the field to undergo evaluation "over the next few hours".
The concluding match of the series at the SCG gets underway on Sunday, 4 January.
The visitors have been without strike bowlers one seamer due to knee trouble and another paceman to a side strain on the current trip.
A replacement bowler was added to the party as cover for Wood.
His form was underwhelming during the first two matches, taking just three wickets.
He was omitted of the third Test, only to be brought back for the fourth Test as Archer's replacement.
Surrey's Atkinson showed better form in Melbourne, claiming a couple of wickets in Australia's first innings, and scoring 28 runs with the bat being one of only three England players to reach double figures.
Post a single over late on the first day, he came back on Saturday morning and dismissed the nightwatchman taken by the wicketkeeper.
Yet, towards the conclusion of the fifth over, he sent down a variation to Travis Head and suddenly grabbed for his hamstring.
The English bowler returned to the side for the Melbourne match following his omission the previous Test.
