Fast bowler Atkinson Adds to the English team's Injury Problems.
'Serious blow' for the touring side after Atkinson is forced off suffering a hamstring problem.
Gus Atkinson increased the injury concerns plaguing England upon exiting the playing area on the second morning of the Boxing Day Test against Australia.
Atkinson experienced discomfort in his hamstring immediately following a delivery in his spell on Saturday.
Team management reported the 27-year-old felt some "soreness" and was to take time off the field to undergo evaluation "during the day".
The concluding match of the series in Sydney begins this coming Sunday.
The visitors have been without strike bowlers Mark Wood with a knee problem and Jofra Archer with an abdominal strain on the current trip.
A replacement bowler was added to the party as injury reinforcement.
The seamer had a tough time during the first two matches, managing only three wickets.
He was dropped of the third Test, only to be brought back for the fourth Test to fill the void.
Surrey's Atkinson showed better form in Melbourne, taking two wickets in Australia's first innings, and scoring 28 runs as a batsman as one of just three English batsmen to get into double digits.
Following a brief spell in Australia's second innings, he came back on Saturday morning and dismissed the nightwatchman Scott Boland caught behind.
Unfortunately, towards the conclusion of the fifth over, he sent down a slower ball to the batsman and suddenly grabbed for his hamstring.
Atkinson returned to the side for the Melbourne match after being left out the previous Test.
