Paceman Gus Atkinson Compounds England's Injury Concerns.
'Serious blow' for the touring side after Atkinson goes off due to a hamstring issue.
Gus Atkinson added to England's injury problems after leaving the field early on day two of the Boxing Day Test against Australia.
The right-arm seamer experienced discomfort in his left leg immediately following a delivery in his spell during the morning session.
The England team reported the 27-year-old had experienced "tightness" and required time away from the action for further assessment "in the coming hours".
The series decider of the series at the SCG starts this coming Sunday.
The English side has been without key quicks Mark Wood to a knee injury and another paceman with an abdominal strain on the current trip.
Matthew Fisher was added to the party to provide backup.
Atkinson struggled during the first two matches, managing only three wickets.
He was omitted from the previous Test, only to be brought back for the Boxing Day match as Archer's replacement.
The county bowler performed better in the fourth Test, taking two wickets with the ball, then making 28 with the bat as one of just three teammates who passed ten runs.
Post a single over late on the first day, he returned for the second day's play and had nightwatchman Scott Boland caught behind.
Yet, on the final ball of that over, he delivered a change of pace to the batsman and promptly felt for his hamstring.
Gus Atkinson returned to the side for the fourth Ashes Test having missed the Adelaide game.
