India paceman Zaheer Khan was summoned for a disciplinary hearing by the International Cricket Council (ICC) match referee after their crushing win over Australia in the second Test on Tuesday.
Khan was called up before referee Chris Broad after he appeared to say something to opener Matthew Hayden following the batsman's dismissal before tea on Monday's fourth day.
India won by 320 runs to take a 1-0 lead in the four-match series.
The bowler, fielding in the deep, ran towards Hayden as he made his way back to the pavilion before turning towards his celebrating team mates. Hayden gestured at the umpire before walking off.
Australia skipper Ricky Ponting confirmed the hearing.
Players from both sides were involved in verbal exchanges during the match and the umpires stepped in more than once, including on the final morning.
Khan also exchanged words with Australian wicketkeeper Brad Haddin during the drawn first test in Bangalore while he making a crucial fifty as the hosts salvaged a draw.
