Paceman Atkinson Exacerbates England's Injury Problems.
'Serious blow' for the touring side after Atkinson is forced off with a hamstring injury.
Gus Atkinson further complicated England's injury problems after leaving the field during Saturday's play in the Melbourne Test in the Ashes series.
Atkinson experienced discomfort in his left leg immediately following a delivery in his spell during the morning session.
Team management indicated the 27-year-old had experienced "tightness" and was to take time away from the action to undergo evaluation "over the next few hours".
The final Test of the tour at the SCG gets underway at the end of the week.
The English side has previously lost strike bowlers one seamer with a knee problem and another paceman with an abdominal strain on the current trip.
Matthew Fisher was brought into the squad as injury reinforcement.
His form was underwhelming in the opening two Tests, claiming a mere three wickets.
He was dropped of the third Test, then recalled for the Boxing Day match as Archer's replacement.
The county bowler showed better form in Melbourne, bagging two scalps during the host's first knock, and scoring 28 runs with the bat as one of just three England players to get into double digits.
After bowling one over in Australia's second innings, he resumed for the second day's play and removed Scott Boland edging to the keeper.
Yet, on the final ball of the fifth over, he bowled a slower ball to Travis Head and promptly felt his left hamstring.
Gus Atkinson was brought back for the Melbourne match after being left out of the third.
