Jonathan Trott has been ruled out of action for three to four weeks meaning he will miss the end of the English domestic season, after scans revealed a fracture to his right hand, but is expected to be fit for the start of the tour to India.

Trott took a blow from Dale Steyn during the fourth ODI against South Africa at Lord's on Sunday and although initial x-rays did not reveal serious damage further investigation has found an undisplaced fracture on his middle finger.

It means Trott will be unavailable for the CB40 final against Hampshire at Lord's and the final round of Championship matches, although Warwickshire are on the brink of securing the four-day title with a game to spare.

An ECB statement said: "Although initial X-rays were clear, a subsequent MRI scan revealed a fracture at the base of his third metacarpal. No intervention is required and the 31-year-old should be able to resume batting in 3-4 weeks and is expected to available for the tour of India next month."

Jonny Bairstow took Trott's place for the final one-day international against South Africa at Trent Bridge and Ravi Bopara moved up to No. 3 but fell for a second ball duck to Dale Steyn.

England are expected to name their Test squad for India next week before the start of the World Twenty20 in Sri Lanka. There are a number of issues to resolve, not least whether Kevin Pietersen will be available but also the likely absence of Ian Bell for the Mumbai Test as his wife is due to give birth.
