Paceman Gus Atkinson Adds to England's Fitness Worries.
'Significant concern' for the touring side after Atkinson goes off suffering a hamstring problem.
The English seamer increased the fitness woes of the England squad upon exiting the playing area during Saturday's play in the Melbourne Test versus the Australians.
The right-arm seamer pulled up with his left leg after the final ball of the fourth over on Saturday.
The touring camp indicated the 27-year-old had experienced "tightness" and required time on the sidelines to undergo evaluation "in the coming hours".
The final Test of the tour beginning on 4 January starts on Sunday, 4 January.
The visitors have already lost strike bowlers one seamer to a knee injury and another paceman with an abdominal strain on this Ashes tour.
Matthew Fisher was added to the party as injury reinforcement.
Atkinson struggled early in the series, claiming a mere three wickets.
He was dropped for the Adelaide match, then recalled for the Boxing Day match as Archer's replacement.
Atkinson improved at the MCG, bagging two scalps in Australia's first innings, then making 28 while batting being one of only three English batsmen who passed ten runs.
After bowling one over in Australia's second innings, he returned for the second day's play and dismissed the nightwatchman Scott Boland caught behind.
Yet, on the final ball of his spell, he bowled a slower ball to the batsman and immediately felt for his hamstring.
Gus Atkinson was recalled for the Boxing Day Test after being left out the previous Test.
