Sri Lankan cricket board was examining stump microphone audios to determine whether captain Kumar Sangakkara or any of his teammates had played a role in coaxing Suraj Randiv to bowl a 'no-ball' to prevent Virender Sehwag from scoring a century.

Sources said that SLC had sought the tapes from the official broadcasters to investigate as what transpired between the bowler and his teammates during the fag end of the tri-series match.
