Cricket South Africa said Monday they had banned four players for involvement in match fixing practices during 2015.

The banned players were named as Jean Symes, Pumelela Matshikwe, Ethy Mbhalati and Thami Tsolekile, the former South African Test wicketkeeper.

"The banning of these four players follows a lengthy investigation," said the organisation in a statement.

The players have been banned from the sport for between seven to 12 years.
