Seamer Gus Atkinson Compounds the English team's Fitness Worries.
'Significant concern' for the English camp after Atkinson goes off suffering a hamstring problem.
The English seamer further complicated England's injury problems after leaving the ground early on day two of the fourth Ashes Test against Australia.
The right-arm seamer felt a problem in his hamstring immediately following a delivery that he bowled at the MCG.
The England team indicated Atkinson felt some "soreness" and would spend time on the sidelines for further assessment "during the day".
The final Test in this Ashes battle beginning on 4 January gets underway at the end of the week.
The visitors have already lost strike bowlers one seamer with a knee problem and another paceman because of a side injury on this Ashes tour.
A replacement bowler was brought into the squad as cover for Wood.
His form was underwhelming in the opening two Tests, claiming a mere a handful of scalps.
He was left out from the previous Test, only to be brought back 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 as one of just three English batsmen who passed ten runs.
Post a single over in Australia's second innings, he resumed the next day and removed Scott Boland taken by the wicketkeeper.
Yet, on the final ball of his spell, he bowled a slower ball to the batsman and immediately felt for his hamstring.
The English bowler was recalled for the Melbourne match after being left out the Adelaide game.
