Rogers suffers dizzy spell, retires hurt

Australia's strong position in the Investec Test at Lord's was overshadowed on the fourth morning by the worrying sight of Chris Rogers retiring hurt after an apparent dizzy spell as he stood at the non-striker's end.

Rogers had added five runs to his overnight score to reach 49 not out, and then watched David Warner play out a maiden from Mark Wood in the second over of the day. At the completion of the over he kneeled down in the middle and expressed his distress.

Warner was quickly at Rogers' side, before the Australian team doctor Peter Brukner and the physio Alex Kountouris ran onto the ground. After a few minutes' consultation Rogers was helped from the field and the No. 3 batsman Steven Smith walked out in his place.

It was an unsettling sight, given that Rogers had been struck in the helmet during his first innings of 173. The blow on the second morning had caused a cut above his right ear, though Rogers continued to bat after treatment.

A Cricket Australia spokesperson said Rogers suffered a dizzy spell on the ground and was being monitored in the Australian dressing room. He had not left the ground, nor gone to hospital.

Earlier on Australia's overseas double tour of England and the West Indies, Rogers had been struck in the helmet by the Dominican net bowler Anderson Burton and missed the two Caribbean Tests due to concussion.

He was also struck in the helmet last summer while fielding at short leg against India in Brisbane, a hit that Rogers admitted had briefly caused him to consider his future.

Cricket Australia has introduced more rigorous procedures for dealing with concussion for the summer of 2015-16, adopting the sorts of policies used in the AFL and NRL competitions in Australia.

The new policy states in part: "Under the concussion policy a player who shows symptoms of concussion is obliged to leave the field for a full concussion assessment by the most qualified medical officer present. If an assessment of concussion is suspected the player must leave the field for a full concussion test and can't return until they are cleared by a medical officer."

Rogers had to this point enjoyed his final Lord's Test, and had spoken widely of his plans to end his international career at the conclusion of this tour.
