Kolkata Knight Riders [ Images ] bowling coach Wasim Akram [ Images ] might have dropped a bombshell by claiming that bowlers in IPL III have been tampering with the ball but KKR captain Sourav Ganguly [ Images ] said he was not aware of any such malpractice.

Akram said that bowlers rubbed red soil on the ball at places like Jaipur [ Images ], Mumbai [ Images ] and Ahmedabad [ Images ], making it difficult for batsmen to sight it at the later stages of a match under floodlights.

Asked about Akram's claim, Ganguly said he was not aware of such ball tampering.

"No idea about it. I am hearing it for the first time," said Ganguly.

Rajasthan Royals [ Images ] captain Shane Warne [ Images ] gave a sarcastic reply when asked about the claim by the former Pakistan captain.

"Maybe he (Akram) is an expert, I am not. I have got no idea about it. We go out and play. I don't agree with it. Maybe I should ask Wasim if he can help me out," said Warne.

"I don't know. It's first I am hearing about ball tampering. I think Wasim has heard about it a little bit more," he added.
