Paceman Gus Atkinson Exacerbates the English team's Fitness Problems.
'Significant concern' for the touring side as Atkinson is forced off with a hamstring injury.
The English seamer further complicated the injury concerns plaguing England when he left the ground early on day two of the Boxing Day Test in the Ashes series.
The right-arm seamer experienced discomfort in his left leg post-delivery of the fourth over during the morning session.
The England team stated the 27-year-old had experienced "tightness" and was to take time off the field for further assessment "over the next few hours".
The series decider in this Ashes battle at the SCG gets underway on Sunday, 4 January.
England have previously lost key quicks one seamer to a knee injury and another paceman because of a side injury during this series.
Matthew Fisher was brought into the squad as injury reinforcement.
The seamer had a tough time early in the series, claiming a mere a handful of scalps.
He was dropped for the Adelaide match, only to be brought back for the Boxing Day match in the playing XI.
Atkinson showed better form in Melbourne, taking two wickets during the host's first knock, and scoring 28 runs while batting being one of only three English batsmen to get into double digits.
After bowling one over late on the first day, he returned the next day and dismissed the nightwatchman taken by the wicketkeeper.
Unfortunately, at the end of that over, he bowled a change of pace to the batsman and immediately felt his left hamstring.
The English bowler was brought back for the Boxing Day Test following his omission of the third.
