Pato limped out of Sunday’s league win over Atalanta on Sunday.
Reports suggest that Pato may have suffered a recurrence of the adductor injury that recently kept him out of action for two months.
“We will have to wait 24 to 48 hours before knowing the extent of the injury,” said Milan vice-president Adriano Galliani.
“Not to have Pato would be terrible. We don’t have anyone who can replace him. Without him, we would need to change our tactical set-up.”
