India's left-arm paceman Zaheer Khan was on Tuesday charged with breaching cricket's international code of conduct after an on-field exchange with Australia's Matthew Hayden during the second Test.
Zaheer, 30, was cited by match referee Chris Broad after exchanging words with Hayden and pointing him to the pavilion after the opening batsman's dismissal by Harbhajan Singh.
Hayden had complained to on-field umpire Rudi Koertzen, who was standing at square leg, when he left the ground after being trapped leg before by Singh for 29 in the over before lunch.
Zaheer has been charged with a Level 2 offence for conduct contrary to the spirit of the game, an the International Cricket Council (ICC) statement said, and was set to attend a disciplinary hearing with Broad.
He runs the risk of a fine or a suspension from either one Test match or two one-day internationals.
Hayden and Singh clashed during India's tour of Australia this year, when the Australian described the spinner as an "obnoxious weed." Singh later called Hayden a "big liar."
Khan's performance was pivotal as India crushed Australia by 320 runs to go 1-0 up in the four-Test series on Tuesday.
