The 23-year-old, along with defender Raul Rodriguez Navas, was not included in the squad for the team's Copa del Rey game at Celta Vigo on Thursday and the club later explained his situation.
"Luca Sangalli suffered a mild stroke this morning. He is currently in the stroke unit of the Donostia University Hospital, where he will be studied," Real Sociedad said in a statement.
