Paceman Atkinson Compounds the English team's Fitness Worries.
'Significant concern' for England as Atkinson goes off due to a hamstring issue.
The pace bowler increased the fitness woes of the England squad when he left the playing area during Saturday's play in the Melbourne Test against Australia.
Atkinson pulled up with his left leg after the final ball in his spell during the morning session.
Team management stated the 27-year-old felt some "soreness" and was to take time off the field to undergo evaluation "over the next few hours".
The final Test in this Ashes battle at the SCG starts on Sunday, 4 January.
England have previously lost strike bowlers Mark Wood with a knee problem and another paceman with an abdominal strain on the current trip.
A replacement bowler was called up to provide backup.
Atkinson struggled during the first two matches, taking just three wickets.
He was omitted of the third Test, then recalled for the Melbourne Test as Archer's replacement.
Surrey's Atkinson improved at the MCG, bagging two scalps in Australia's first innings, then making 28 while batting being one of only three England players who passed ten runs.
Following a brief spell at the end of day one, he resumed for the second day's play and dismissed the nightwatchman Scott Boland caught behind.
However, on the final ball of his spell, he sent down a variation to Travis Head and promptly felt for his hamstring.
The English bowler was brought back for the Melbourne match having missed of the third.
