Seamer Gus Atkinson Adds to England's Fitness Concerns.
'Serious blow' for the touring side after Atkinson is forced off with a hamstring injury.
Gus Atkinson further complicated the injury concerns plaguing England after leaving the ground during Saturday's play in the Melbourne Test versus the Australians.
The pace bowler felt a problem in his hamstring post-delivery that he bowled during the morning session.
The touring camp indicated the 27-year-old reported "discomfort" and would spend time on the sidelines in order to be assessed "during the day".
The concluding match of the tour at the SCG starts at the end of the week.
The visitors have already lost strike bowlers one seamer with a knee problem and another paceman to a side strain on the current trip.
A replacement bowler was added to the party to provide backup.
His form was underwhelming during the first two matches, managing only a handful of scalps.
He was left out from the previous Test, only to be brought back for the Melbourne Test as Archer's replacement.
The county bowler showed better form in Melbourne, claiming a couple of wickets during the host's first knock, then making 28 while batting being one of only three English batsmen to reach double figures.
After bowling one over late on the first day, he returned for the second day's play and dismissed the nightwatchman taken by the wicketkeeper.
However, at the end of the fifth over, he bowled a change of pace to Travis Head and promptly felt at his leg.
Atkinson returned to the side for the fourth Ashes Test after being left out the previous Test.
