Parsons had cartilage damage in his right knee. The arthroscopic procedure Friday was done by team physician Dr. T.O. Souryal.
Parsons just finished the first season of a three-year, $46 million contract. He averaged 15.7 points and 4.9 rebounds in 66 games, all starts. He missed the last six games of the regular season and all but the opener in a 4-1 first-round playoff loss to Houston, his former team.
The 26-year-old Parsons might be one of just four players under contract for next season, depending on whether other potential free agents opt out of current deals.
