Paceman Gus Atkinson Compounds England's Injury Worries.
'Major setback' for the touring side after Atkinson goes off due to a hamstring issue.
The English seamer increased the fitness woes of the England squad upon exiting the field early on day two of the fourth Ashes Test in the Ashes series.
The pace bowler experienced discomfort in his left leg immediately following a delivery that he bowled on Saturday.
The England team reported Atkinson felt some "soreness" and was to take time off the field in order to be assessed "in the coming hours".
The concluding match of the tour at the SCG begins at the end of the week.
England have been without strike bowlers Mark Wood due to knee trouble and Jofra Archer with an abdominal strain on the current trip.
A replacement bowler was added to the party as cover for Wood.
The seamer had a tough time in the opening two Tests, taking just three wickets.
He was dropped of the third Test, then recalled for the Melbourne Test to fill the void.
Atkinson performed better in the fourth Test, taking two wickets during the host's first knock, and scoring 28 runs with the bat being one of only three England players to get into double digits.
Following a brief spell in Australia's second innings, he returned the next day and removed Scott Boland edging to the keeper.
However, towards the conclusion of his spell, he delivered a change of pace to Travis Head and immediately felt at his leg.
The English bowler was brought back for the fourth Ashes Test after being left out of the third.
