Seamer Atkinson Exacerbates the English team's Injury Problems.
'Major setback' for the English camp as Atkinson goes off due to a hamstring issue.
The pace bowler further complicated England's injury problems when he left the field during Saturday's play of the Boxing Day Test against Australia.
The pace bowler experienced discomfort in his left leg post-delivery of the fourth over at the MCG.
The touring camp reported Atkinson felt some "soreness" and would spend time on the sidelines for further assessment "in the coming hours".
The series decider in this Ashes battle in Sydney gets underway on Sunday, 4 January.
England have already lost fast bowlers one seamer with a knee problem and Jofra Archer to a side strain on the current trip.
A replacement bowler was added to the party to provide backup.
Atkinson struggled early in the series, managing only a handful of scalps.
He was omitted for the Adelaide match, then recalled for the Melbourne Test as Archer's replacement.
The county bowler showed better form in Melbourne, bagging two scalps during the host's first knock, before adding 28 as a batsman among just a trio of English batsmen to reach double figures.
Following a brief spell at the end of day one, he came back the next day and had nightwatchman Scott Boland caught behind.
However, at the end of his spell, he bowled a slower ball to Travis Head and promptly felt his left hamstring.
Atkinson returned to the side for the fourth Ashes Test following his omission the previous Test.
