Tipoff is scheduled for 8:00 PM ET at Xfinity Mobile Arena (formerly Wells Fargo Center) in Philadelphia, Pennsylvania.

The game is broadcast on Peacock and NBC Sports Network. The Celtics hold a 3-2 series advantage after the 76ers forced Game 6 with a convincing 113-97 road victory in Game 5 at TD Garden, powered by a strong fourth-quarter surge.

Team Records and Context

Boston Celtics: Finished the 2025-26 regular season 56-26 (.683), securing the No. 2 seed in the East (strong home record of 30-11). They boast elite two-way play, depth, and championship pedigree, with a top-tier net rating during the season.

Philadelphia 76ers: Ended at 45-37 (.549), earning the No. 7 seed after navigating the play-in (including a win over Orlando). They rely heavily on star power from Joel Embiid and Tyrese Maxey but have shown inconsistency, especially defensively.

Boston is the clear favorite to close out the series on the road, though Philadelphia’s home crowd and recent momentum create elimination-game tension. A potential Game 7 would return to Boston on Saturday, May 2.

Recent Form

Celtics: They dominated early, winning Game 1 by 32 points (123-91) and Game 4 by 32 points (128-96). However, they dropped Games 2 and 5 at home (97-111 and 97-113), showing vulnerability when their offense stalls. Boston has looked dominant when clicking on both ends but has allowed Philly to force turnovers and dictate pace in losses.

76ers: After a blowout loss in Game 1 and tight Game 3 defeat (100-108), Philadelphia stole Game 2 on the road and delivered a statement 16-point win in Game 5. Embiid and Maxey combined for 58 points in Game 5, with Philly outscoring Boston 28-11 in the fourth quarter. The Sixers have shown resilience and the ability to exploit Boston’s occasional offensive lulls, but they were overwhelmed in Boston’s blowout wins.

Series History and Head-to-Head

This is the latest chapter in one of the NBA’s most storied rivalries (23rd playoff series all-time, with Boston holding a significant historical edge, including winning the last six series). In the 2025-26 regular season, the teams split 2-2, with Philly taking two early close games (including a 117-116 opener) and Boston winning the later matchups more decisively (e.g., 114-98).

Playoff series so far (Boston leads 3-2):

Game 1: Celtics 123, 76ers 91

Game 2: 76ers 111, Celtics 97

Game 3: Celtics 108, 76ers 100

Game 4: Celtics 128, 76ers 96

Game 5: 76ers 113, Celtics 97

Boston has won the blowouts with superior efficiency and rebounding, while Philly’s wins have featured strong guard play and fourth-quarter execution.

Key Player Matchups

Jayson Tatum & Jaylen Brown (Celtics wings) vs. Philadelphia’s perimeter defenders: Tatum (returning from injury earlier) and Brown provide scoring, playmaking, and defense. They combined for 50 points in Game 3. Philly must contain their creation without over-helping.

Joel Embiid (76ers C) vs. Boston’s frontcourt (Al Horford, Kristaps Porzingis if available, or versatile bigs): Embiid was dominant in Game 5 with 33 points, 8 assists. His post presence and passing are critical for Philly, but Boston’s switching and help defense have limited him in blowout losses.

Tyrese Maxey (76ers PG) vs. Derrick White / Jrue Holiday (or Boston’s backcourt): Maxey’s speed and scoring (25+ points in Game 5 with rebounds/assists) fuel Philly’s attack. Boston’s elite guard defense aims to disrupt his rhythm and force tough shots.

Supporting casts: Boston gets energy from Payton Pritchard, Sam Hauser, and versatile forwards. Philly leans on Kelly Oubre Jr., and role players for rebounding and three-point shooting.

Boston’s depth and defensive versatility have been decisive in their wins, while Philly’s star duo has kept them alive.

Injury Report

Celtics: Largely healthy heading into Game 6, with no major injuries reported in recent games. The team has benefited from a full or near-full rotation, contributing to their blowout performances.

76ers: Joel Embiid has returned from post-appendectomy recovery and played effectively in Game 5 (probable/available status recently cleared). Kelly Oubre Jr. has been monitored for adductor soreness in prior games but is expected to be available unless new issues arise. Depth pieces may still be limited, but the core is intact for this must-win.

Betting Trends

Boston has covered big in their series wins but has been vulnerable at home in losses.

Series totals have varied widely due to blowouts vs. competitive games.

Road favorites in elimination scenarios can be tricky, but Boston’s superior regular-season metrics and historical playoff dominance against Philly provide an edge.

Rebounding and defensive rating have favored Boston in most games.
