The Sea Robbers have opted not to extend the contracts of the four players after its expiry on June 30.
A busy transfer season is expected at Orlando Pirates after the Soweto giants confirmed a release of another four players.
Richard Ofori, Siyabonga Mpontshane, Kermit Erasmus and Thabang Monare are the latest players to be let go just a couple of days after the exit of Fortune Makaringe and Souaibou Marou.
The four players did not have much to do in the concluded season – after being sidelined by coach Jose Riveiro, as the club successfully defended their MTN8 and Nedbank Cup titles. For the second time in a row, the Sea Robbers finished behind Mamelodi Sundowns in the Premier Soccer League, meaning they will be playing in the Caf Champions League in the forthcoming campaign.
