West Indies spinner Sulieman Benn has been banned for one Test after pleading guilty to behaviour "contrary to the spirit of the game".
Benn, 28, received the sanction from match referee Jeff Crowe for a level two breach of the International Cricket Council's code of conduct.
The incident occurred during the lunch break of the third Test between West Indies and South Africa in Barbados when Benn entered the South Africa dressing room uninvited.
"Benn inappropriately and without invitation entered the South Africa team dressing room in Kensington Oval and provoked some South Africa players and team management," said the ICC.
"This provocation resulted in a heated exchange of aggressive remarks."
Crowe added: "Whatever had gone on before Sulieman entered the Proteas' dressing room, while helping to explain his behaviour, cannot justify it."
There had been an earlier on-field incident between Benn and South Africa fast bowler Dale Steyn, who was fined 100 percent of his match fee after being found guilty of spitting in the direction of Benn.
"Clearly, Sulieman has acted inappropriately here and in a way that is contrary to the spirit of cricket," said Crowe.
"We like the game to be played in a competitive way but, whether on or off the field, players must treat the opposition and the game itself with respect. That did not happen on this occasion and Sulieman has paid the price."
Benn's ban is for one Test, two one-day internationals or two Twenty20 internationals, whichever comes first.
South Africa won the third Test by seven wickets to secure a 2-0 series success.
