Fast bowler Atkinson Adds to England's Fitness Concerns.
'Major setback' for the touring side after Atkinson goes off suffering a hamstring problem.
The English seamer increased the fitness woes of the England squad after leaving the playing area on the second morning of the fourth Ashes Test in the Ashes series.
The right-arm seamer experienced discomfort in his hamstring post-delivery that he bowled on Saturday.
The England team reported Atkinson had experienced "tightness" and would spend time on the sidelines to undergo evaluation "during the day".
The concluding match of the tour in Sydney starts at the end of the week.
England have previously lost fast bowlers Mark Wood to a knee injury and Jofra Archer with an abdominal strain on the current trip.
Matthew Fisher was called up to provide backup.
The seamer had a tough time early in the series, managing only three wickets.
He was left out of the third Test, only to be brought back for the fourth Test to fill the void.
The county bowler improved at the MCG, claiming a couple of wickets with the ball, and scoring 28 runs while batting among just a trio of England players who passed ten runs.
Following a brief spell in Australia's second innings, he resumed on Saturday morning and had nightwatchman edging to the keeper.
Unfortunately, on the final ball of the fifth over, he bowled a variation to the batsman and suddenly grabbed at his leg.
The English bowler was recalled for the Melbourne match after being left out the previous Test.
