Cape Town - Cricket South Africa (CSA) expressed their continuing concern on Tuesday over the amount of South African players signing a Kolpak contract.
The Cape Cobras decided to part ways with Wayne Parnell after the Proteas all-rounder signed a three-year Kolpak deal with English county club, Worcestershire.

General manager cricket of CSA Corrie van Zyl stated in the Cobras' press release that the country's board is looking at a way to protect itself against Kolpak deals.
"Every franchise is entitled to select two Kolpak players in their playing eleven, but those Kolpak players must be paid from the franchise's own funds, and therefore it is really up to the franchises to determine the value of that player to their team," said Van Zyl, who played two ODIs and coached the national side.
"We are concerned about the amount of players who have signed a Kolpak agreement, which makes them unavailable for national selection. Although the experience of the Kolpak players is valuable, CSA needs to ensure that those players, who are still committed to playing for the Proteas in the future, are afforded the opportunities to develop.
"Every player who turns Kolpak, is one less that can be eligible for the South African team and therefore CSA needs to look at ways to protect itself against the loss of experienced and younger players," Van Zyl adds.
"Our mandate is to produce players at domestic level who will represent South Africa."
The Kolpak ruling allows counties to employ foreign cricketers who comply with its regulations as 'home' players.
Players who sign Kolpak deals in England are unavailable for South Africa in international cricket.
There are currently 13 South Africans playing under a Kolpak contract in England this season, those including former Proteas cricketers Morne Morkel, Kyle Abbott, Simon Harmer and Colin Ingram.
