Seamer Atkinson Compounds the English team's Fitness Concerns.
'Serious blow' for the touring side after Atkinson is forced off due to a hamstring issue.
The pace bowler further complicated the fitness woes of the England squad after leaving the playing area on the second morning of the fourth Ashes Test against Australia.
The pace bowler felt a problem in his left hamstring post-delivery in his spell at the MCG.
The touring camp indicated the 27-year-old felt some "soreness" and required time away from the action in order to be assessed "over the next few hours".
The concluding match in this Ashes battle beginning on 4 January starts this coming Sunday.
England have already lost fast bowlers one seamer to a knee injury and another paceman with an abdominal strain on this Ashes tour.
Matthew Fisher was brought into the squad as injury reinforcement.
His form was underwhelming early in the series, taking just three wickets.
He was omitted from the previous Test, only to be brought back for the fourth Test to fill the void.
The county bowler improved at the MCG, taking two wickets with the ball, before adding 28 with the bat as one of just three England players who passed ten runs.
After bowling one over late on the first day, he came back the next day and removed Scott Boland edging to the keeper.
Yet, on the final ball of his spell, he sent down a change of pace to Travis Head and immediately felt his left hamstring.
Gus Atkinson returned to the side for the Boxing Day Test following his omission of the third.
