The Boston Celtics and Philadelphia 76ers are expected to play a regular-season game Jan. 11 at O2 Arena in London, according to an NBA source who said the game has yet to be finalized by the league.

The Boston Herald first reported that the teams are scheduled to play in England. It would be a home game for the 76ers.

The NBA will release its 2017-18 schedule in August. As part of the league’s Global Games, news of this matchup could be released before the regular schedules.

The last time the 76ers went overseas was during the 2013-14 preseason, when they played Bilbao Basket in Spain and the Oklahoma City Thunder in Manchester, England. The Celtics played preseason games in Spain and Italy in 2015.

SUMMER LEAGUE: The Boston Celtics led from start to finish and ran the Golden State Warriors off the court with a 20-5 first quarter en route to a 93-69 victory at Las Vegas.

Boston (4-0) didn’t play, or miss, the last two No. 3 picks in the draft in Jaylen Brown and Jayson Tatum. Jabari Bird, a 2017 second-round pick, took advantage of the opening with 17 points on 8-of-10 shooting. Ante Zizic, the 2016 No. 23 overall pick, had a double-double with 14 points and 10 rebounds to go with three blocks. Reserve forward Rosco Allen scored 18.

WIZARDS: Washington matched the Brooklyn Nets’ $106 million, four-year offer sheet to keep forward Otto Porter, making him the team’s highest paid player.

Porter’s new deal puts his salary ahead of guards Bradley Beal and John Wall. He set career highs with 13.4 points, 6.4 rebounds and 1.5 steals per game last season, his fourth as a professional. He finished fourth in the NBA with a 3-point shooting percentage of .434.

“Otto has developed into a vital part of our young core, which is why we made it clear that our priority was to keep him here to maintain continuity and build on the success of this group heading into next season and beyond,” team president Grunfeld said in a statement. “His versatility, basketball IQ and three-point shooting combine to make him a great fit for us on the floor while his character and work in the community show why we’re so pleased to have him as a cornerstone of our franchise.”

KNICKS-ROCKETS: The New York Knicks and Houston Rockets are still trying to work out a deal involving Carmelo Anthony, though it may take some time – if it happens.

Anthony has a no-trade clause and would have to agree to any deal. He has told the Knicks he would waive the no-trade clause to go to Houston or Cleveland.

The Knicks have been trying to trade the All-Star forward, but finding a deal is difficult. Anthony is 33 and still has two years and $54 million remaining on his contract.

A trade would reunite Anthony with Rockets Coach Mike D’Antoni, who resigned as Knicks coach in March 2012 in part over his frustration with Anthony’s unwillingness to embrace his offense.

But the Rockets have two elite distributors in Paul and James Harden, and Anthony can possibly settle into the spot-up shooter role he’s played in the Olympics, where he’s won a record three gold medals.

JAZZ: A person with direct knowledge of the deals said Utah reached agreements to sign free agents Thabo Sefolosha, Jonas Jerebko and Ekpe Udoh.

Jerebko played the past three seasons with the Boston Celtics.

The Jazz also released Boris Diaw, whose 2017-18 salary would have been guaranteed Saturday.

Diaw was a valued and versatile big man in his lone season with the Jazz but his departure was expected after the team tried to trade his expiring contract. The 14-year veteran posted on Instagram, “THANK YOU JAZZ AND JAZZ FANS, It was a great season, I appreciated every aspects of my experience here. I wish you the best for the years to come.”

None of the three additions will offset Hayward’s signing with the Celtics.
