Antonio Cassano is set to spend a second night in hospital as tests try to ascertain what caused his fainting spell.
Milan have only confirmed that the striker was “taken ill” as the team returned from Rome and landed at the Malpensa airport and is at the Policlinico hospital in Milan.
According to the latest reports, Cassano had a fainting spell in the airport, his vision was blurred and he had difficulty speaking.
The 29-year-old was kept overnight in the Neurology department of the clinic and will be there for at least one more night to undergo tests.
Clearly, Cassano will not fly out with the rest of the Milan squad for Tuesday's Champions League trip to BATE Borisov.
