The Celtics signed guard Hayden Gray and forward Gabe McGlothan on September 24, pushing the offseason roster count past twenty. Jayson Tatum remains day-to-day with left knee and leg soreness, with an estimated return of October 1, seven days before Boston's preseason opener at Cleveland.
Boston keeps adding names before it plays a game.
Hayden Gray and Gabe McGlothan joined the Celtics on September 24, the same week Hoops Rumors grouped Boston into a roundup of minor transactions across seven teams. Gray already has experience with the franchise, one game for 24.8 minutes and 6.0 points last season; McGlothan arrives as a rookie at 27. Boston still has not named a candidate for the two-way contract that a September 12 report first flagged as open.
Tatum's return date now sits before the preseason opener.
Tatum is listed day-to-day with left knee and leg soreness, an estimated return of October 1. That is a week ahead of Boston's preseason opener at Cleveland on October 8, and nineteen days ahead of the regular-season opener at Detroit on October 20.
The payroll is already set regardless of who wins a camp spot.
Boston's payroll stands at $203.9 million, above the $200.4 million luxury tax line, with Tatum's $58.5 million and George's $54.1 million the two largest numbers on the books. Gray and McGlothan are fighting for spots at the bottom of a twenty-name group competing for a roster that has little room left to add money.
The schedule is finally on the calendar.
Boston opens preseason October 8 at Cleveland, then hosts Philadelphia on October 10 and Charlotte on October 14, and visits Philadelphia again on October 16, before the regular-season opener October 20 at Detroit, broadcast on NBC and Peacock.

When is Jayson Tatum expected back from his knee injury?
Tatum is day-to-day with left knee and leg soreness, with an estimated return of October 1, ahead of Boston's October 8 preseason opener at Cleveland.
