BOSTON — Terry Rozier scored 15 points and grabbed 10 rebounds as the Boston Celtics beat the Philadelphia 76ers 113-96 in an exhibition game Monday despite resting stars Kyrie Irving, Al Horford and Gordon Hayward.

Celtics Coach Brad Stevens said the lineup he went with Monday allows him to take a good look at what will be Boston’s second unit.

“I feel really good about where we are, considering we’re 13 days in,” Stevens said. “I don’t think we’re by any means a finished product and I think we can get better.”

Semi Ojeleye had 16 points off the bench for the Celtics to lead all scorers. Jaylen Brown added 12 points and nine rebounds, and Marcus Smart had 12 points and six assists. No. 3 draft pick Jayson Tatum scored seven points in 23 minutes of action.

Ben Simmons had 15 points and six rebounds for the 76ers. Furkan Korkmaz added 13 points and Markelle Fultz, the No. 1 pick in the draft, scored 12.

Celtics center Aron Baynes sprained his left knee in the first half.

ROCKETS 117, KNICKS 95: James Harden had 36 points, 11 assists and nine rebounds, and Houston made 22 3-pointers while remaining unbeaten and keeping New York winless in the preseason.

Tim Hardaway Jr. scored 21 points for the Knicks.

PISTONS 107, PACERS 97: Detroit outscored Indiana 30-15 from the 3-point line, and had a 26-11 edge in points off turnovers.

NOTES

76ERS: A person familiar with the situation told The Associated Press the Philadelphia 76ers and Joel Embiid have agreed on a maximum contract extension.

The person spoke on condition of anonymity because the contract has not been officially announced. The person said Embiid and the Sixers have agreed on a $148 million, five-year extension and it could reach even more if the 7-foot center reaches certain incentives.

HEAT: Dwyane Wade and LeBron James are starting together again. Cavaliers Coach Tryonn Lue announced that Wade will start at shooting guard alongside Derrick Rose in Cleveland’s remodeled backcourt. Wade recently signed as a free agent with the Cavs, reuniting with James after the two stars spent four seasons together in Miami. He replaces J.R. Smith, who will come off the bench after starting 112 games over the past two seasons.
