Maradona, 58, "has decided not to continue in his position as manager of Dorados. Under his doctors' advice, he will be devoting time to his health and will undergo two operations: for his shoulder and his knee," lawyer Matias Morla wrote on Twitter.
"We thank the entire Dorados family and will continue the dream together in the future," he added.
Maradona took the coaching job at Dorados, who are based in the western state of Sinaloa, in September 2018 -- amusing skeptics who questioned why the 1986 World Cup champion, who has publicly battled various addictions, would move to a place better known for drug cartels than football.
But he answered his critics by coaching the struggling club to back-to-back finals appearances that brought them tantalizingly close -- but not quite -- to their dream of winning promotion to the first division.
