Paceman Gus Atkinson Adds to England's Fitness Concerns.
'Significant concern' for England after Atkinson is forced off with a hamstring injury.
The English seamer increased the fitness woes of the England squad after leaving the ground during Saturday's play of the Boxing Day Test against Australia.
The right-arm seamer pulled up with his hamstring post-delivery that he bowled at the MCG.
The England team indicated the 27-year-old reported "discomfort" and would spend time off the field in order to be assessed "during the day".
The final Test in this Ashes battle at the SCG begins at the end of the week.
The visitors have been without fast bowlers one seamer to a knee injury and another paceman with an abdominal strain during this series.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time in the opening two Tests, managing only three wickets.
He was omitted of the third Test, then recalled for the fourth Test in the playing XI.
Atkinson performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs with the bat among just a trio of England players to reach double figures.
Post a single over in Australia's second innings, he resumed on Saturday morning and had nightwatchman taken by the wicketkeeper.
Unfortunately, on the final ball of that over, he bowled a slower ball to the batsman and promptly felt for his hamstring.
The English bowler was brought back for the Boxing Day Test having missed of the third.
