Paceman Gus Atkinson Adds to the English team's Fitness Problems.
'Serious blow' for the touring side after Atkinson goes off due to a hamstring issue.
The pace bowler further complicated England's injury problems upon exiting the field on the second morning of the Boxing Day Test in the Ashes series.
Atkinson experienced discomfort in his left leg after the final ball that he bowled during the morning session.
The touring camp reported Atkinson felt some "soreness" and would spend time on the sidelines to undergo evaluation "over the next few hours".
The concluding match of the tour at the SCG starts at the end of the week.
The English side has previously lost fast bowlers one seamer due to knee trouble and another paceman with an abdominal strain on the current trip.
A replacement bowler was added to the party as cover for Wood.
His form was underwhelming in the opening two Tests, managing only three wickets.
He was omitted of the third Test, only to be brought back for the Boxing Day match to fill the void.
Surrey's Atkinson performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs as a batsman as one of just three English batsmen to get into double digits.
Post a single over at the end of day one, he came back on Saturday morning and dismissed the nightwatchman Scott Boland caught behind.
Yet, on the final ball of the fifth over, he bowled a slower ball to the batsman and immediately felt for his hamstring.
Atkinson was recalled for the Melbourne match having missed the previous Test.
