Paceman Gus Atkinson Adds to England's Fitness Problems.
'Major setback' for the touring side as Atkinson goes off due to a hamstring issue.
The English seamer increased England's injury problems when he left the playing area during Saturday's play of the Boxing Day Test against Australia.
The pace bowler experienced discomfort in his left hamstring immediately following a delivery of the fourth over during the morning session.
The England team stated Atkinson felt some "soreness" and would spend time off the field for further assessment "during the day".
The final Test of the series beginning on 4 January begins this coming Sunday.
England have already lost key quicks Mark Wood due to knee trouble and another paceman to a side strain on the current trip.
Matthew Fisher was brought into the squad as injury reinforcement.
The seamer had a tough time early in the series, taking just three wickets.
He was omitted from the previous Test, before being recalled for the Melbourne Test in the playing XI.
The county bowler showed better form in Melbourne, bagging two scalps with the ball, and scoring 28 runs as a batsman being one of only three teammates to reach double figures.
Post a single over in Australia's second innings, he returned on Saturday morning and removed Scott Boland edging to the keeper.
However, on the final ball of that over, he bowled a change of pace to Travis Head and suddenly grabbed for his hamstring.
The English bowler was brought back for the Boxing Day Test following his omission the Adelaide game.
