President Silvio Berlusconi will not be present at Milanello today as the club start their pre-season preparations.
The owner was expected to make an appearance as the Italian champions begin work for the 2011-12 campaign.
However, the Italian Primer Minister has withdrawn from the appointment following the death of an Italian soldier in Afghanistan last night.
Milan will meet up with 28 squad players on Tuesday, but Zlatan Ibrahimovic and Antonio Cassano won't be there.
The Rossoneri will also be without their four squad members who are on Copa America duty – Thiago Silva, Alexandre Pato, Robinho and Mario Yepes.
