Vice-president Galliani claimed on Friday that he would be stepping away from San Siro due to his reputation being "seriously damaged" by ongoing turmoil at the Serie A giants.
Reports had suggested that Berlusconi's daughter, Barbara, would assume day-to-day control of running club affairs.
"Serenity has returned to AC Milan. Adriano Galliani will remain in his position," Berlusconi told ANSA.
Galliani himself refused to confirm Berlusconi's claim as the squad departed for Catania ahead of Sunday's Serie A clash.
He told the club's official website: "It is not up to me to comment on the words of president Berlusconi."
Meanwhile, Stephan El Shaarawy is included in Massimiliano Allegri's squad for the trip to Sardinia and could make his first appearance since September after a foot injury.
