The Buccaneers lost 1-0 to Etoile du Sahel in Sousse on Sunday, having drawn the first leg 1-1 in Soweto the weekend before.
Bucs pair Menzi Masuku and Gift Motupa have since linked up with the South Africa U-23 team in Senegal, as Owen Ga Gama's side prepare for today's U-23 AFCON clash with Zambia in Dakar.
Pirates said on Twitter: "The Buccaneers are heading to Tunis ahead of their return flight to OR Tambo International Airport, scheduled to arrive Wednesday at 10H50."
