Celtics vs. Mavericks live score: Updated Game 3 results, highlights from 2024 NBA Finals

The 2024 NBA Finals shift to Dallas in what is, historically, a must-win game for the Mavericks.

The Celtics protected the parquet, taking care of business at home to build a 2-0 series lead. Boston held Dallas to a playoff-low 89 points in Game 1, then overcame one of its worst 3-point shooting games of the season to edge out a victory in Game 2.

It has been a balanced effort on the Celtics end, as Jayson Tatum, Jaylen Brown, Jrue Holiday, Derrick White and Kristaps Porzingis have all scored double figures in each of the first two Finals games. Boston will be without Porzingis for Game 3, though, as he deals with a “rare” leg injury that has his status in jeopardy for the rest of the series.

The Mavericks have been more of a one-man show. Luka Doncic is averaging 31.0 points, 10.5 rebounds and 6.0 assists so far but he hasn’t had much help. Kyrie Irving is averaging just 14.0 points on 35.1 percent shooting from the field and Dallas’ role players will need to be significantly better at home than they were on the road.

Will the Mavericks defend home court or will the Celtics put Dallas in a historically insurmountable 3-0 series hole? The Sporting News has you covered with live updates, highlights and more from all the action in Game 3.
