Gimenez sustained a knock to the head during the 2-0 victory at the Vicente Calderon - which was marred by supporter clashes before the game, which resulted in a Deportivo fan passing away - but played the remainder of the game before going for tests.
Once a neurological exam and a cranial CT scan had been completed, the Uruguayan was admitted to the Monteprincipe Hospital for overnight observation.
"Jose Maria Gimenez was discharged from the hospital this morning after spending the night for observation at the Monteprincipe Hospital," read a statement on the Spanish champions' website.
"The centre-back was transferred to the FREMAP clinic in Majadahonda, where he underwent a neurological exam and a cranial CT scan. Once the tests were complete, he was admitted to the Monteprincipe Hospital."
