The Celtics will control the Nos. 28 and 32 picks in the first and second rounds of the draft, respectively, and will need to find some cheap talent to help fill out their already costly roster if they hope to continue contending for titles when star forward Jayson Tatum returns from his torn Achilles tendon injury.

If a player is seriously injured, his team can apply for the disabled-player exception to replace him. An NBA-designed physician would have to determine that the player is “substantially more like than not” to be out through June 15 next season for it to be granted.

Once the sale of the Celtics is officially approved by the NBA’s Board of Governors, likely later this summer, Chisholm’s group will purchase 51 percent of the team at that time. Grousbeck will remain on as lead governor until the balance closes after the 2027-28 season.
