Fast bowler Atkinson Compounds the English team's Fitness Worries.

'Major setback' for the English camp after Atkinson leaves the field with a hamstring injury.

Gus Atkinson further complicated England's injury problems upon exiting the ground during Saturday's play of the Boxing Day Test versus the Australians.

The pace bowler pulled up with his left hamstring immediately following a delivery of the fourth over at the MCG.

The touring camp indicated the 27-year-old had experienced "tightness" and was to take time on the sidelines for further assessment "over the next few hours".

The final Test of the tour in Sydney gets underway this coming Sunday.

The English side has previously lost fast bowlers Mark Wood due to knee trouble and another paceman because of a side injury on this Ashes tour.

Matthew Fisher was added to the party to provide backup.

The seamer had a tough time early in the series, managing only a handful of scalps.

He was dropped of the third Test, before being recalled for the Melbourne Test in the playing XI.

The county bowler performed better in the fourth Test, taking two wickets during the host's first knock, before adding 28 while batting being one of only three England players to get into double digits.

Post a single over late on the first day, he came back the next day and dismissed the nightwatchman edging to the keeper.

However, on the final ball of the fifth over, he sent down a change of pace to Travis Head and promptly felt his left hamstring.
