Milan defender Philippe Mexes has been diagnosed with an eye condition that will keep him out for at least a week.
The Frenchman pulled out during the warm-up of last night’s 1-1 draw with Genoa  complaining of pain in his left eye.
He was taken to the local hospital and underwent specialist tests that diagnosed a slight central serous retinopathy (CSR).
This is an eye disease which causes visual impairment in one eye, often due to fluid under the retina.
He will rest until next Friday when the defender will have further tests.
