Paceman Gus Atkinson Adds to England's Injury Concerns.
'Significant concern' for the touring side as Atkinson goes off due to a hamstring issue.
The pace bowler added to the fitness woes of the England squad after leaving the playing area during Saturday's play of the Boxing Day Test versus the Australians.
The pace bowler experienced discomfort in his hamstring immediately following a delivery of the fourth over on Saturday.
Team management reported the 27-year-old reported "discomfort" and was to take time away from the action to undergo evaluation "during the day".
The series decider of the series beginning on 4 January begins at the end of the week.
The visitors have been without key quicks Mark Wood due to knee trouble and another paceman to a side strain on the current trip.
A replacement bowler was added to the party to provide backup.
Atkinson struggled during the first two matches, taking just a handful of scalps.
He was left out for the Adelaide match, only to be brought back for the fourth Test in the playing XI.
The county bowler showed better form in Melbourne, bagging two scalps in Australia's first innings, before adding 28 while batting as one of just three England players to get into double digits.
Post a single over late on the first day, he returned the next day and dismissed the nightwatchman Scott Boland caught behind.
Yet, at the end of the fifth over, he delivered a variation to the batsman and suddenly grabbed at his leg.
The English bowler was recalled for the fourth Ashes Test following his omission the previous Test.
