The Boston Celtics and Philadelphia 76ers will meet in Game 6 of their first-round NBA playoff series Thursday night at Xfinity Mobile Arena on Peacock.

The No. 2-seeded Celtics missed an opportunity to advance at home Tuesday when they fell 113-97 to the seventh-seeded 76ers — the fourth consecutive win by a road team in the series.

Philadelphia is seeking to become the 14th team to win a playoff series after trailing 3-1 (teams holding that edge advance nearly 96% of the time). The 76ers are 0-18 in series when trailing 3-1 (but twice have forced a Game 7), and the Celtics are 32-0 in series with a 3-1 lead (twice being pushed to a Game 7).

This is the record 22nd playoff meeting between Philadelphia and Boston, which holds 15-7 edge. It's been 44 years since the 76ers' last playoff series win over the Celtics.

Boston Celtics vs. Philadelphia 76ers game preview:

It's been up and down for the Celtics, who have become the first playoff team in NBA history to win multiple games by at least 30 points and lose multiple games by double digits.

Cold shooting doomed Boston in the fourth quarter of its Game 5 loss. The Celtics led by a point through three quarters before being outscored 28-11 in the fourth, their lowest-scoring quarter of the season. Boston was 3 of 22 from the field, including 1 for 14 on 3-pointers, and missed its final 14 shots.

“It just wasn't good enough from us," said Jaylen Brown, who had 22 points on 9 of 23 shooting. "It wasn't good enough on my behalf. We just got to be better."

The 76ers rode the performance of center Joel Embiid, who scored 33 points in only his second game back from appendectomy surgery. Embiid also had eight assists in his eighth playoff game with at least 30 points against the Celtics (one short of Wilt Chamberlain’s franchise record against any single opponent).

“I want to do anything I can to win a basketball game," Embiid said. "I just want to enjoy this moment. I’ve pushed very hard to come back to try and help as much as I can. I’m just thankful to be in a position where I get to play. I don’t know how long I have that I can do this.

It was tough because I had some complications after the surgery. I don’t want to get into the detail.”

Said teammate Tyrese Maxey, who added 25 points and 10 rebounds: "(Embiid) was dominant, especially in the second half. I was proud of him tonight. He can be (Shaquille O'Neal) or he could be Dirk Nowitzki some days. He’s just a strong individual. He’s skilled, too, so that makes it tough.”
