Parsons has been dealing with a recurring right knee injury and sat out of Tuesday's Game 2 loss to the Houston Rockets. He was re-evaluated on Wednesday, after which the team made the decision. Dallas said Parsons is "currently exploring surgical options to address his right knee injury."
Parsons' knee problems forced him to miss the team’s final six regular season games, but he did play in Game 1 of the series, scoring 10 points in 37 minutes.
The Mavericks are down 0-2 as the series shifts to Dallas for Game 3 on Friday.
Parsons, 26, averaged 15.7 points, 2.4 assists and 4.9 rebounds per game this season for the Mavericks.
