NEW YORK — The Golden State Warriors will open their title defense by hosting Houston in Chris Paul’s Rockets debut on Oct. 17, the NBA’s earliest opening night in 37 years.

Cleveland and Boston will play an Eastern Conference finals rematch earlier that night to begin the 2017-18 season, the league announced Thursday.

The Warriors and Cavaliers will play a Finals rematch on Christmas, the marquee game of the five-game holiday schedule.

The other Christmas games are:

— Philadelphia, playing on Dec. 25 for the first time since 2001, at New York

— Washington at Boston in the Celtics’ first Christmas home game ever

— Houston at Oklahoma City in a matchup of MVP Russell Westbrook and runner-up James Harden

— Minnesota at the Lakers and No. 2 pick Lonzo Ball in the nightcap

The NBA moved up the start of its 72nd regular season in hopes of creating more opportunities for players to rest without doing so during games. The Oct. 17 opener is the league’s earliest since the 1980-81 season began on Oct. 10.

National TV games during the opening week and the Christmas schedule were unveiled Thursday. The complete schedule is being finalized and will be announced next week.

The Oct. 18 schedule features the 76ers potentially debuting the last two No. 1 picks at Washington. Ben Simmons sat out all last season with a foot injury, and Philadelphia then grabbed guard Markelle Fultz in June after trading with Boston to move up to No. 1.

Jimmy Butler makes his Timberwolves debut in the nightcap of that ESPN doubleheader in San Antonio, while the Oct. 19 games feature Paul George and Oklahoma City hosting the Knicks.

Celtics to play 76ers in London in January

LONDON (AP) — The Boston Celtics and Philadelphia 76ers will travel to London in January for a game at The O2 arena.

The Sixers are the home team for the Jan. 11 game. Tickets for the NBA London Game 2018 game go on sale in October.

The game will mark the NBA’s eighth regular-season game in London and the Celtics’ second game in the capital, having played a preseason game against the Minnesota Timberwolves in 2007.

The 76ers will be playing their second game in the UK and first game in London, having previously played a preseason game in Manchester against the Oklahoma City Thunder in 2013.

Because the Sixers are the home team, season-ticket holders with automatic payment plans will not be charged for one game. Season-ticket holders who have paid in full can request a full refund or roll over the charges for future game purchases.

The Sixers went 28-54 last season and the Celtics had the best record in the Eastern Conference at 53-29.
