Fast bowler Gus Atkinson Compounds England's Fitness Problems.
'Significant concern' for the touring side as Atkinson is forced off due to a hamstring issue.
Gus Atkinson increased the fitness woes of the England squad when he left the field during Saturday's play of the fourth Ashes Test against Australia.
The pace bowler felt a problem in his left leg immediately following a delivery in his spell during the morning session.
The touring camp stated the 27-year-old felt some "soreness" and required time away from the action to undergo evaluation "over the next few hours".
The series decider in this Ashes battle beginning on 4 January begins on Sunday, 4 January.
The English side has been without key quicks one seamer due to knee trouble and another paceman because of a side injury on the current trip.
Matthew Fisher was called up as cover for Wood.
His form was underwhelming in the opening two Tests, taking just a handful of scalps.
He was left out from the previous Test, before being recalled for the Melbourne Test in the playing XI.
The county bowler showed better form in Melbourne, taking two wickets with the ball, before adding 28 with the bat among just a trio of teammates to reach double figures.
Following a brief spell late on the first day, he returned on Saturday morning and dismissed the nightwatchman taken by the wicketkeeper.
Unfortunately, towards the conclusion of that over, he delivered a variation to the batsman and suddenly grabbed for his hamstring.
Gus Atkinson returned to the side for the Melbourne match having missed of the third.
