The New York Knicks will raise their championship banner on NBA's opening night on Oct. 20, as they face LeBron James and his debut with the Philadelphia 76ers (7 p.m. ET), the NBA announced Tuesday.

The Boston Celtics at Detroit Pistons open the tripleheader on NBC in a rare matinee (3 p.m. ET), while the Oklahoma City Thunder play the San Antonio Spurs (9:30 ET) to close it out in a West finals rematch.

The Celtics suffered a first-round playoff exit last season, while the Pistons advanced to the Eastern Conference semifinals.

The Golden State Warriors also play at the Los Angeles Lakers that day, with the Cleveland Cavaliers at 76ers and Nuggets at Thunder on Oct. 22.
