Paceman Gus Atkinson Adds to the English team's Injury Problems.
'Serious blow' for the touring side as Atkinson is forced off suffering a hamstring problem.
The pace bowler further complicated the fitness woes of the England squad upon exiting the ground during Saturday's play of the Boxing Day Test against Australia.
The right-arm seamer felt a problem in his left hamstring immediately following a delivery that he bowled on Saturday.
Team management reported the 27-year-old felt some "soreness" and would spend time on the sidelines to undergo evaluation "during the day".
The final Test of the tour in Sydney gets underway this coming Sunday.
The English side has already lost fast bowlers one seamer to a knee injury and another paceman with an abdominal strain on the current trip.
Matthew Fisher 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 omitted from the previous Test, before being recalled for the fourth Test to fill the void.
Atkinson performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs while batting being one of only three English batsmen to reach double figures.
Post a single over in Australia's second innings, he returned on Saturday morning and removed Scott Boland Scott Boland caught behind.
Unfortunately, on the final ball of his spell, he bowled a change of pace to the batsman and immediately felt his left hamstring.
Atkinson returned to the side for the fourth Ashes Test following his omission of the third.
