"BCCI's suspect action review committee found the extension of his (Ghosh) arm and elbow above permissible level and he should undergo rehabilitation. He's barred from playing the BCCI tournaments till his action is cleared," BCCI's chief administrative officer Ratnakar Shetty wrote in a letter to the CAB.
During Bengal's Ranji Trophy away match against Rajasthan, which was the 30-year-old seamer's only match this season, his action was reported by the field umpires B K Ravi and K Srinath.
Now the onus is with Bengal to correct Ghosh's action before being cleared by the NCA for the seamer to play again.
Bengal coach Ashok Malhotra said he would try to correct his action after the end of the season.
"I came to know of the decision today itself. I will sit with the pacer as soon as the Ranji ties are over," Malhotra said.
