Dallas Mavericks News

Confirmed Lineup: Luka Doncic, Kyrie Irving, Derrick Jones Jr., PJ Washington, Daniel Gafford

• Olivier-Maxence Prosper (ankle) — Available

Doncic averaged 32.4 points, 9.6 rebounds, and 8.2 assists in the Western Conference Finals. He'll need to continue that stellar play against the Celtics, who haven't faced much healthy competition throughout the postseason. Doncic appeared against Boston twice this season and had incredible outings, posting 35.0 points, 15.0 rebounds, and 12.0 assists per contest, but Dallas lost both of those games.

Irving has a history with Boston, which he spoke about on Monday. "I wasn't my best self during that time," Irving said. "It was just a chapter in my life that I got to enjoy for the most part. We had a great opportunity to do some special things, but it was cut short, just based off personal reasons on my end."

Boston Celtics News

Confirmed Lineup: Jrue Holiday, Derrick White, Jaylen Brown, Jayson Tatum, Al Horford

• Kristaps Porzingis (calf) — Said he'll play

After missing the previous 10 games, Porzingis will return to the floor as the Celtics host the Mavs for Game 1 of the Finals. He spoke about his return on Wednesday, seeming unsure how he will respond after his extended absence. "Tomorrow will be my first minutes in a while," Porzingis said. "I did as much as I could to prepare for this moment, but there’s nothing like game minutes and game experience ... it’ll be tough to jump into the Finals like this, but I did everything I could to prepare for it." There's a possibility that Porzingis could be limited in his first game back, but that hasn't been explicitly confirmed by him or coach Mazzulla. The Celtics have lost just two games during the postseason en route to this series.
