Pakistani cricketer Shahid Afridi faced a ban of upto four Tests or eight one-dayers after being charged with bringing the game into disrepute in the first one-day international against South Africa.
Afridi was seen pushing his bat at a spectator who said something to him on his way back to the pavilion after being dismissed in the match at Centurion on Sunday.
The Match Referee had initially refused to bring any charges against the player but ICC Chief Executive Malcolm Speed decided to act after studying the video of the incident.
"Afridi has been charged with a Level 3 offence under section C 2 of the Code which refers to 'conduct unbecoming ... Which could bring (players or officials or) the game of cricket into disrepute," a statement from the ICC said.
The release said the hearing will be conducted by Chris Broad, a member of the ICC Elite Panel of Match Referees, and will take place as soon as possible and details of its timing will be released in due course.
If found guilty, Afridi could be banned for two to four Tests, or four to eight one-dayers.
Until the hearing takes place, Afridi remains available to play for Pakistan.
South African batsman Herschelle Gibbs was banned for a Test, a one-dayer and a Twenty-20 International for racial remarks at a section of the crowd in the first Test earlier in the series.
