Paceman Gus Atkinson Exacerbates England's Fitness Problems.

The pace bowler further complicated England's injury problems after leaving the field early on day two of the Boxing Day Test versus the Australians.

The pace bowler felt a problem in his left hamstring immediately following a delivery of the fourth over on Saturday.

The England team stated the 27-year-old had experienced "tightness" and would spend time on the sidelines for further assessment "over the next few hours".

The final Test in this Ashes battle in Sydney begins on Sunday, 4 January.

The visitors have already lost fast bowlers Mark Wood to a knee injury and another paceman because of a side injury on the current trip.

Matthew Fisher was brought into the squad as cover for Wood.

The seamer had a tough time during the first two matches, managing only three wickets.

He was dropped of the third Test, before being recalled for the Boxing Day match to fill the void.

Surrey's Atkinson performed better in the fourth Test, claiming a couple of wickets during the host's first knock, then making 28 as a batsman among just a trio of England players to reach double figures.

Post a single over in Australia's second innings, he resumed on Saturday morning and had nightwatchman Scott Boland caught behind.

Yet, at the end of that over, he delivered a change of pace to Travis Head and suddenly grabbed at his leg.
