Harbhajan Singh will work under Bruce Elliott, the biomechanics expert from Australia, to correct his action. Harbhajan's doosra, the delivery that leaves the right-handed batsmen, was recently reported by Chris Broad, the match referee for India's series against Bangladesh, and he was give six weeks to complete the corrective procedure and report back to the International Cricket Council.

SK Nair, the secretary of the Indian board, confirmed this to Reuters: "We have identified Bruce Elliott for Harbhajan to work on his action and we have informed the ICC on the action we are taking." Nair added that the ICC had extended the deadline until February 18 following a request by the BCCI.

Ravi Shastri, Laxman Sivaramakrishnan and Javagal Srinath were also expected to be on the experts' panel and Nair said that the BCCI were awaiting their acceptance of the assignment.

Harbhajan action had earlier come under scrutiny in 1998 but he was cleared after after undergoing remedial work in London.
