Paceman Gus Atkinson Adds to the English team's Fitness Worries.
'Serious blow' for the touring side after Atkinson goes off due to a hamstring issue.
Gus Atkinson increased England's injury problems after leaving the field early on day two of the Boxing Day Test against Australia.
The pace bowler experienced discomfort in his hamstring after the final ball in his spell at the MCG.
The England team stated Atkinson had experienced "tightness" and would spend time away from the action to undergo evaluation "during the day".
The concluding match of the series at the SCG starts this coming Sunday.
The English side has been without key quicks Mark Wood due to knee trouble and Jofra Archer because of a side injury during this series.
Matthew Fisher was added to the party as injury reinforcement.
His form was underwhelming in the opening two Tests, taking just three wickets.
He was dropped from the previous Test, before being recalled for the fourth Test to fill the void.
Surrey's Atkinson improved at the MCG, taking two wickets with the ball, before adding 28 with the bat as one of just three English batsmen who passed ten runs.
After bowling one over late on the first day, he returned on Saturday morning and removed Scott Boland taken by the wicketkeeper.
Unfortunately, towards the conclusion of that over, he sent down a variation to Travis Head and promptly felt for his hamstring.
The English bowler was brought back for the Boxing Day Test following his omission the previous Test.
