Milan, Nov 2: AC Milan is due to announce what is ailing hospitalized striker Antonio Cassano.
The Italy forward has been at the Policlinico facility since Saturday, when he was taken for tests after falling ill on Milan's plane following the team's 3-2 victory over Roma.
Cassano was reportedly joking with teammates on the plane, before suddenly developing problems with his vision, speech and movement.
Speculation over the cause has ranged from a mini stroke to a heart problem that requires surgery.
Milan was preparing to release a formal statement in conjunction with the hospital on Wednesday.
Cassano missed the 1-1 draw with BATE Borisov on Tuesday that qualified Milan for the next round of the Champions League.
