Midfielder Jonas Gutierrez was dropped by Newcastle United because of his testicular cancer diagnosis in 2013, an employment tribunal has found.
The 32-year-old was suing the Magpies for in the region of £2m on the grounds of disability discrimination.
The tribunal also ruled the club made it impossible for the Argentina international to trigger a further deal through appearances.
Claims of unfavourable treatment and another of harassment related to disability were dismissed.
A further remedy hearing will be held in due course, in which compensation will be addressed.
Gutierrez now plays for Deportivo La Coruna in Spain.
