The 32-year-old former Orlando Pirates and Mamelodi Sundowns attacker initially joined Wydad on loan in 2025 after following former Brazilians boss Rulani Mokwena to the Moroccan Botolo Pro league team.
He ultimately signed a permanent deal and went on to play 30 games in all competitions, scoring eight goals and providing four assists.
He most recently came on as a substitute in the 2-1 CAF Confederations Cup Group B defeat to AS Maniema Union.
