India spinner Harbhajan Singh has been reported again for using a suspected illegal bowling action, this time in the second Test against Pakistan.
India won the match by 195 runs, with Harbhajan taking four wickets.
Match referee Chris Broad made the decision to report the off-spinner, after consultation with on-field umpires Darrell Hair and Steve Bucknor.
"The report relates specifically to the bowler's action when delivering the doosra," said Broad.
"It was noticeable to the umpires and me that there was an apparent change in action when bowling this delivery between the first innings of the match, when no concerns were raised, and the second, which then prompted the report to be made."
The doosra is an off-spinner's delivery that spins in the opposite direction, like a leg-break.
It was Broad who reported the spinner after a Test in Bangladesh in December, and he was only cleared earlier this month when the rules were loosened.
The International Cricket Council will now deal with the case.
Under the terms of their bowling review process, Harbhajan will undergo analysis of his action by 'human movement' specialists.
A bio-mechanical review of his action should reveal whether the 24-year-old's action falls within the 15 degrees of permitted elbow straightening.
He remains eligible for selection for India, who lead Pakistan 1-0 in their current series with the third and final match beginning in Bangalore on Thursday.
