Fast bowler Atkinson Compounds England's Injury Worries.

Gus Atkinson added to England's injury problems when he left the field during Saturday's play of the fourth Ashes Test versus the Australians.

The pace bowler experienced discomfort in his hamstring immediately following a delivery in his spell at the MCG.

The touring camp indicated the 27-year-old reported "discomfort" and was to take time on the sidelines to undergo evaluation "during the day".

The final Test in this Ashes battle at the SCG gets underway on Sunday, 4 January.

England have already lost key quicks one seamer with a knee problem and another paceman to a side strain on this Ashes tour.

A replacement bowler was added to the party to provide backup.

Atkinson struggled early in the series, managing only a handful of scalps.

He was dropped of the third Test, only to be brought back for the fourth Test in the playing XI.

Atkinson showed better form in Melbourne, bagging two scalps during the host's first knock, then making 28 as a batsman as one of just three English batsmen to reach double figures.

After bowling one over at the end of day one, he came back on Saturday morning and removed Scott Boland edging to the keeper.

Yet, on the final ball of his spell, he sent down a slower ball to Travis Head and immediately felt his left hamstring.
