The Bulls will open the 2015-16 NBA season against the defending Eastern Conference champion Cavaliers on Oct. 27 at the United Center, according to the Chicago Tribune.
The NBA will announce its full schedule during a one-hour special at 5 p.m. CT Wednesday.
The Bulls and Cavaliers are expected to once again be two of the top teams in the Eastern Conference. The Cavs eliminated the Bulls from the playoffs in six games during the Eastern Conference semifinals last season.
News of the Bulls playing on Christmas previously leaked Tuesday, when The Oklahoman reported the Bulls would travel to Oklahoma City to face the Thunder.
