The Spain international sustained a muscular injury in his right femoral biceps ahead of the encounter.
A club statement on Wednesday read: “After the tests carried out today by the Real Madrid Medical Services, our player Isco has been diagnosed with a muscular injury in the right femoral biceps.
“His recovery will continue to be monitored.”
