Seamer Gus Atkinson Compounds England's Fitness Problems.
'Major setback' for the touring side after Atkinson goes off with a hamstring injury.
The pace bowler added to the fitness woes of the England squad upon exiting the ground during Saturday's play of the Boxing Day Test in the Ashes series.
The right-arm seamer experienced discomfort in his hamstring post-delivery in his spell during the morning session.
The England team reported Atkinson had experienced "tightness" and would spend time on the sidelines to undergo evaluation "in the coming hours".
The series decider of the tour in Sydney begins this coming Sunday.
The visitors have already lost fast bowlers one seamer to a knee injury and Jofra Archer to a side strain on the current trip.
A replacement bowler was added to the party as injury reinforcement.
Atkinson struggled early in the series, claiming a mere a handful of scalps.
He was left out for the Adelaide match, then recalled for the Boxing Day match in the playing XI.
Atkinson showed better form in Melbourne, claiming a couple of wickets in Australia's first innings, before adding 28 as a batsman being one of only three teammates to reach double figures.
After bowling one over in Australia's second innings, he came back for the second day's play and had nightwatchman taken by the wicketkeeper.
Unfortunately, on the final ball of his spell, he bowled a slower ball to the batsman and promptly felt his left hamstring.
Atkinson was recalled for the fourth Ashes Test following his omission of the third.
