Seamer Atkinson Adds to the English team's Injury Worries.
'Significant concern' for the touring side after Atkinson goes off with a hamstring injury.
Gus Atkinson further complicated the fitness woes of the England squad after leaving the playing area on the second morning of the Boxing Day Test against Australia.
The pace bowler experienced discomfort in his hamstring post-delivery in his spell at the MCG.
The England team indicated the 27-year-old felt some "soreness" and required time away from the action to undergo evaluation "in the coming hours".
The final Test of the series at the SCG starts at the end of the week.
England have been without fast bowlers one seamer due to knee trouble and Jofra Archer because of a side injury on the current trip.
Matthew Fisher was brought into the squad as injury reinforcement.
Atkinson struggled in the opening two Tests, managing only three wickets.
He was omitted from the previous Test, only to be brought back for the fourth Test to fill the void.
Atkinson performed better in the fourth Test, claiming a couple of wickets in Australia's first innings, then making 28 as a batsman among just a trio of English batsmen to reach double figures.
After bowling one over at the end of day one, he came back the next day and had nightwatchman taken by the wicketkeeper.
Unfortunately, at the end of his spell, he delivered a slower ball to Travis Head and suddenly grabbed at his leg.
Atkinson was recalled for the Boxing Day Test following his omission of the third.
