Fast bowler Gus Atkinson Adds to the English team's Injury Problems.
'Significant concern' for the touring side as Atkinson is forced off with a hamstring injury.
The English seamer increased the fitness woes of the England squad upon exiting the playing area early on day two in the Melbourne Test versus the Australians.
The pace bowler pulled up with his hamstring post-delivery that he bowled during the morning session.
The England team stated the 27-year-old felt some "soreness" and was to take time away from the action for further assessment "in the coming hours".
The series decider in this Ashes battle beginning on 4 January begins on Sunday, 4 January.
The English side has previously lost key quicks one seamer with a knee problem and another paceman with an abdominal strain on the current trip.
A replacement bowler was called up to provide backup.
The seamer had a tough time during the first two matches, managing only a handful of scalps.
He was omitted for the Adelaide match, only to be brought back for the Boxing Day match as Archer's replacement.
The county bowler improved at the MCG, bagging two scalps with the ball, and scoring 28 runs as a batsman among just a trio of England players to get into double digits.
Following a brief spell at the end of day one, he came back for the second day's play and removed Scott Boland edging to the keeper.
However, at the end of his spell, he delivered a slower ball to Travis Head and promptly felt for his hamstring.
Gus Atkinson returned to the side for the Boxing Day Test after being left out of the third.
