Glenn McGrath has been officially reprimanded for breaching the ICC Code of Conduct during his country's third Test match against South Africa at Sydney.

In a hearing after play on the fourth day, McGrath was found to have breached Level 1.4 of the ICC Code which relates to "using language that is obscene, offensive or insulting and/or the making of an obscene gesture" by Chris Broad, the ICC Match Referee.

The charge was brought by on-field umpires Aleem Dar, Billy Bowden and the third umpire Bob Parry. The hearing was attended by Steve Bernard, Australian team manager, Ricky Ponting, the Australia captain, Glenn McGrath and the on-field umpires.

McGrath had Herschelle Gibbs dropped by Shane Warne from the first ball of the over, and Gibbs finished it with consecutive boundaries to frustrate the bowler, for which McGrath showed dissent.

McGrath is the second Australian to be reprimanded in this Test match after Brett Lee was pulled up for showing dissent on Day 1.
