Toronto FC terminated the contract of defender Geovanny Caicedo on Friday by mutual consent.
The 30-year-old Caicedo, an Ecuador international, joined Toronto in January from Ecuadorian club LDU Quito.
"We are certainly disappointed with this outcome," said Toronto FC coach and technical director Aron Winter.
"During the preseason Geovanny expressed difficulty adjusting to the style of Major League Soccer. This reason combined with being away from his family, we were willing to accept the contract termination.
"We felt it was in the best interest of Geovanny. We wish him the best in his future endeavors."
Toronto opens the season March 17 at Seattle Sounders FC.
