Paceman Gus Atkinson Adds to England's Injury Concerns.
'Serious blow' for the touring side after Atkinson is forced off with a hamstring injury.
The pace bowler added to England's injury problems when he left the playing area during Saturday's play of the fourth Ashes Test against Australia.
Atkinson pulled up with his hamstring post-delivery that he bowled during the morning session.
The England team indicated Atkinson had experienced "tightness" and would spend time on the sidelines in order to be assessed "in the coming hours".
The series decider of the tour at the SCG begins at the end of the week.
The English side has been without key quicks one seamer with a knee problem and another paceman to a side strain on the current trip.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time early in the series, claiming a mere a handful of scalps.
He was omitted of the third Test, before being recalled for the fourth Test as Archer's replacement.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps with the ball, before adding 28 with the bat among just a trio of English batsmen who passed ten runs.
After bowling one over at the end of day one, he returned on Saturday morning and removed Scott Boland edging to the keeper.
Unfortunately, towards the conclusion of that over, he bowled a slower ball to the batsman and promptly felt for his hamstring.
Atkinson was recalled for the Melbourne match after being left out the Adelaide game.
