Harbhajan Singh and Mahendra Singh Dhoni have been declared fit for the Test series against South Africa after a test at the National Cricket Academy (NCA) in Bangalore.

"As per the [fitness] report, both the players have recovered from injuries and are available for South Africa Series," Niranjan Shah, the BCCI secretary, said in a statement.

Harbhajan, who was diagnosed as suffering from a hamstring injury after the Australia tour, was put through specific drills at the NCA, including indoor tests and sprints outside under a light drizzle, by the fitness team of Paul Chapman and Paul Close before being declared fit. "I am very much fit," Harbhajan said.

Dhoni was put through routine wicket-keeping drills indoors and an X-ray taken on the injured finger on his right hand.

Both Harbhajan and Dhoni were included by the selectors in the 14-member squad for the first two Tests against South Africa, and were asked to report to the NCA for fitness tests.
