Paceman Gus Atkinson Compounds England's Injury Problems.
'Significant concern' for the English camp after Atkinson goes off with a hamstring injury.
The pace bowler further complicated the injury concerns plaguing England after leaving the playing area early on day two of the Boxing Day Test in the Ashes series.
The pace bowler felt a problem in his left leg after the final ball that he bowled during the morning session.
Team management stated the 27-year-old had experienced "tightness" and required time away from the action in order to be assessed "during the day".
The final Test of the series in Sydney gets underway on Sunday, 4 January.
England have previously lost key quicks one seamer with a knee problem and Jofra Archer with an abdominal strain during this series.
A replacement bowler was added to the party as cover for Wood.
Atkinson struggled during the first two matches, managing only three wickets.
He was left out of the third Test, then recalled for the Boxing Day match to fill the void.
The county bowler improved at the MCG, claiming a couple of wickets during the host's first knock, and scoring 28 runs while batting being one of only three England players to get into double digits.
Post a single over at the end of day one, he came back the next day and removed Scott Boland edging to the keeper.
However, on the final ball of that over, he delivered a slower ball to Travis Head and promptly felt for his hamstring.
The English bowler was recalled for the Boxing Day Test having missed of the third.
