Seamer Gus Atkinson Adds to England's Fitness Problems.
'Major setback' for the touring side after Atkinson goes off suffering a hamstring problem.
The pace bowler further complicated the fitness woes of the England squad upon exiting the playing area during Saturday's play of the Boxing Day Test against Australia.
The pace bowler pulled up with his hamstring post-delivery in his spell on Saturday.
The touring camp stated the 27-year-old felt some "soreness" and was to take time on the sidelines to undergo evaluation "in the coming hours".
The final Test in this Ashes battle beginning on 4 January gets underway at the end of the week.
The English side has already lost fast bowlers one seamer with a knee problem and Jofra Archer to a side strain on the current trip.
A replacement bowler was called up as injury reinforcement.
The seamer had a tough time in the opening two Tests, managing only a handful of scalps.
He was left out for the Adelaide match, before being recalled for the Boxing Day match as Archer's replacement.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps with the ball, before adding 28 with the bat as one of just three English batsmen to reach double figures.
Post a single over late on the first day, he resumed the next day and removed Scott Boland edging to the keeper.
Unfortunately, on the final ball of his spell, he bowled a change of pace to Travis Head and immediately felt his left hamstring.
Gus Atkinson returned to the side for the fourth Ashes Test following his omission of the third.
