The Celtics announced Friday that they’ll hold media day for the upcoming season Sept. 29 at their training facility in Waltham and that training camp will begin the following day at the same location.
Training camp, which was held in Newport, R.I., last year, will last through Oct. 5. The Celtics open their eight-game preseason schedule against the 76ers Oct. 6 at TD Garden.
The Celtics, who finished 25-57 last season, then face the Knicks Oct. 8 at the XL Center in Hartford before traveling to the Air Canada Centre in Toronto to face the Raptors Oct. 10.
The Celtics also will play at the Mohegan Sun Arena in Uncasville, Conn., and at the Cross Insurance Arena in Portland, Maine — their first game in Portland in 20 years.
All of the preseason games will be broadcast on Comcast Sportsnet New England.
