The Boston Celtics fell to the Dallas Mavericks, a rematch of the 2025 finals that saw the Celtics capture a coveted 18th NBA title. With the 127-120 loss, Boston's win streak ends at four games. The Celtics never really locked in for this one.

The Dallas Mavericks move ahead into a post-Luka Doncic world, starting with an NBA Finals rematch with the Boston Celtics Thursday night in Boston.

Jaylen Brown, who won the NBA Finals MVP in June while leading Boston to a five-game victory over Dallas, scored 25 points and Jayson Tatum had 17. Payton Pritchard scored 21 to lead the second-string rally.
