League sources told ESPN the player has been "non-communicative to multiple people close to him inside and outside of the Cavaliers in recent days."
The 29-year-old has recently been dealing with an ankle injury.
Rose injured the ankle Oct. 20 at Milwaukee and has missed several games. The team said last week that Rose’s ankle will be immobilized for a week and he will undergo extended treatment “over the next two to three weeks.”
In his first season with Cleveland, Rose, whose promising career has been slowed by injuries in recent years, is averaging 14.3 points in seven games. The former league MVP signed with the Cavs as a free agent this summer after spending last season with the New York Knicks.
