Paceman Atkinson Compounds England's Injury Problems.
'Significant concern' for the English camp as Atkinson is forced off with a hamstring injury.
The English seamer increased England's injury problems upon exiting the field early on day two in the Melbourne Test against Australia.
The right-arm seamer experienced discomfort in his hamstring post-delivery that he bowled on Saturday.
The England team reported the 27-year-old had experienced "tightness" and would spend time away from the action for further assessment "over the next few hours".
The series decider in this Ashes battle beginning on 4 January gets underway this coming Sunday.
England have previously lost fast bowlers one seamer with a knee problem and another paceman to a side strain on this Ashes tour.
Matthew Fisher was brought into the squad to provide backup.
The seamer had a tough time during the first two matches, taking just a handful of scalps.
He was dropped of the third Test, before being recalled for the Melbourne Test to fill the void.
Surrey's Atkinson performed better in the fourth Test, taking two wickets with the ball, and scoring 28 runs as a batsman as one of just three England players to reach double figures.
After bowling one over at the end of day one, he resumed for the second day's play and removed Scott Boland taken by the wicketkeeper.
Yet, at the end of his spell, he bowled a variation to Travis Head and promptly felt his left hamstring.
Gus Atkinson returned to the side for the fourth Ashes Test after being left out the Adelaide game.
