Aubameyang will undergo surgery on Thursday for a partial tear of the external meniscus in his right knee, a fresh blow for a Deportivo La Coruna side that had built much of its promising start around the veteran striker.
Discomfort that first appeared after the match against Real Betis at Riazor prompted an MRI scan, which confirmed the tear, and the 37-year-old travelled to Madrid on crutches, accompanied by club doctor Mejuto, to be operated on by traumatologist Manuel Leyes at the Centro Olympia.
He is expected to be discharged the same day before returning to A Coruña to begin his recovery, with his return to full training dependent on how the knee responds; the club has not set a firm timeline, though comparable operations typically require four to six weeks, with some estimates for a player of his age stretching towards eight.
It compounds a difficult run for head coach Antonio Hidalgo, who had already lost midfielder Marc Casadó for around three months with a fractured collarbone, and now loses his top scorer for at least five weeks.
Aubameyang had started the season superbly, scoring five goals and providing two assists, including in the 1-1 draw at Getafe, and had become the focal point of Deportivo's attack. Nsongo, Eddahchouri and Yeremay Hernández are the alternatives available to Hidalgo in his absence.
