Milan will face Roma in Serie A at the weekend without veterans Gennaro Gattuso and Gianluca Zambrotta.
The World Cup winning duo limped out of the 3-0 win at Bologna yesterday with injuries which will keep them sidelined until the start of 2011.
Midfield warrior Gattuso picked up a right thigh problem which will need between seven and 10 days to get over.
Zambrotta, meanwhile, suffered a knee injury which isn't as serious as first thought but still bad enough to see him sidelined for up to two weeks.
The Rossoneri, who lead Serie A, have had their injury issues this term considering that Alexandre Pato, Pippo Inzaghi, Mathieu Flamini and Thiago Silva are all on the treatment table.
