Seamer Gus Atkinson Exacerbates the English team's Fitness Problems.
'Serious blow' for the English camp after Atkinson goes off with a hamstring injury.
The pace bowler further complicated the injury concerns plaguing England upon exiting the field during Saturday's play of the fourth Ashes Test against Australia.
The pace bowler pulled up with his left hamstring after the final ball in his spell on Saturday.
The England team indicated the 27-year-old reported "discomfort" and was to take time away from the action in order to be assessed "in the coming hours".
The series decider of the series in Sydney gets underway this coming Sunday.
England have already lost strike bowlers one seamer to a knee injury and another paceman with an abdominal strain on the current trip.
A replacement bowler was added to the party as injury reinforcement.
Atkinson struggled in the opening two Tests, taking just a handful of scalps.
He was left out for the Adelaide match, then recalled for the Melbourne Test as Archer's replacement.
The county bowler showed better form in Melbourne, claiming a couple of wickets with the ball, then making 28 with the bat as one of just three teammates to reach double figures.
Post a single over in Australia's second innings, he returned on Saturday morning and dismissed the nightwatchman Scott Boland caught behind.
Yet, at the end of the fifth over, he sent down a variation to the batsman and promptly felt at his leg.
Atkinson was brought back for the fourth Ashes Test after being left out the previous Test.
