Paceman Atkinson Exacerbates the English team's Injury Problems.
'Significant concern' for England after Atkinson goes off due to a hamstring issue.
The pace bowler added to England's injury problems when he left the playing area during Saturday's play of the Boxing Day Test against Australia.
The right-arm seamer felt a problem in his hamstring after the final ball that he bowled during the morning session.
Team management stated Atkinson felt some "soreness" and would spend time away from the action to undergo evaluation "over the next few hours".
The concluding match of the tour in Sydney begins on Sunday, 4 January.
England have been without fast bowlers one seamer due to knee trouble and another paceman with an abdominal strain on this Ashes tour.
A replacement bowler was brought into the squad to provide backup.
His form was underwhelming early in the series, taking just a handful of scalps.
He was left out of the third Test, before being recalled for the fourth Test as Archer's replacement.
Atkinson performed better in the fourth Test, claiming a couple of wickets with the ball, before adding 28 while batting as one of just three English batsmen to reach double figures.
Post a single over late on the first day, he returned for the second day's play and had 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 brought back for the fourth Ashes Test having missed the previous Test.
