Sunderland have sacked their £8 million ($11m) 2016 signing Papy Djilobodji after the defender breached his contract and failed a fitness test.
The former Chelsea man was allowed to go on unpaid leave throughout July, with the expectation that he would either find a new club or return with the required fitness to play for the Black Cats.
Sunderland claim that he instead returned in September, "ignoring written requests for his return", and "comprehensively failed" a fitness test given to all players during pre-season.
The club have subsequently issued Djilobodji notice that his contract has been terminated.
Djilobodji has endured a nomadic career thus far, and was a surprise signing by Chelsea in 2015.
He failed to make a Premier League appearance for the Blues and was shipped out to the Stadium of Light after just one season, the second half of which he spent at Werder Bremen.
The Black Cats have made a strong start to life in the third tier of English football, however, and sit fourth after seven games, winning four and drawing three.
