The club announced on Tuesday that Isco was set to have an operation but included no time-frame for the 26-year-old's recovery.
"After the tests carried out today on our player Isco, he has been diagnosed with acute appendicitis," a Real Madrid statement read.

"We hope everything goes well and he has a speedy recovery."
