Fast bowler Atkinson Compounds the English team's Injury Problems.
'Serious blow' for the English camp after Atkinson goes off suffering a hamstring problem.
The pace bowler increased England's injury problems when he left the playing area on the second morning of the Boxing Day Test versus the Australians.
Atkinson experienced discomfort in his left hamstring after the final ball of the fourth over on Saturday.
Team management indicated Atkinson felt some "soreness" and required time on the sidelines to undergo evaluation "during the day".
The final Test of the series at the SCG begins on Sunday, 4 January.
England have previously lost key quicks one seamer to a knee injury and Jofra Archer because of a side injury on this Ashes tour.
A replacement bowler was brought into the squad to provide backup.
His form was underwhelming early in the series, managing only a handful of scalps.
He was omitted of the third Test, before being recalled for the Melbourne Test in the playing XI.
The county bowler showed better form in Melbourne, claiming a couple of wickets with the ball, before adding 28 while batting being one of only three English batsmen who passed ten runs.
After bowling one over at the end of day one, he resumed the next day and dismissed the nightwatchman edging to the keeper.
Unfortunately, on the final ball of the fifth over, he delivered a variation to the batsman and immediately felt his left hamstring.
Atkinson was brought back for the fourth Ashes Test after being left out the Adelaide game.
