Hoopsrumors filed two roster roundups on September 30; only the Atlantic Notes item named a Celtic, listing Tatum and Robinson with nothing further attached. The more useful clock counts down to October 8, preseason at Cleveland, and October 20, the regular-season opener at Detroit on NBC and Peacock.
A pair of roundups named two Celtics and explained nothing.
Hoopsrumors grouped Tatum and Robinson into an Atlantic Notes item on September 30, the same day a separate New York Notes roundup touched Boston with no team-specific detail. Neither report carries a transaction, a timeline, or a quote.
Preseason opens in Cleveland before the record means anything.
Boston plays at the Cavaliers on October 8, hosts the 76ers on October 10, hosts the Hornets on October 14, and closes the preseason slate at the 76ers on October 16. The regular season opens October 20 at the Pistons, on NBC and Peacock. The record is 0-0 because none of that has happened yet.
The payroll is already doing work the games haven't started.
Boston carries $203.9 million against a $200.4 million luxury tax line, with Tatum's $58.5 million and George's $54.1 million anchoring the number. Every roster move from here operates under that ceiling before it operates under a coach's preference.
One roster spot has stayed open since before camp began.
The two-way slot flagged September 12 is still unfilled after Max Shulga left September 21 and Boston added Gabe McGlothan and Hayden Gray on September 23; no report has tied either addition to the open spot. Tatum's day-to-day listing and same-day clearance on September 24 are the closest thing to injury news available.
When do the Celtics play their first game of the 2026-27 season?
Boston opens preseason October 8 at the Cavaliers, then hosts the 76ers October 10 and the Hornets October 14 before closing preseason at the 76ers October 16. The regular season opens October 20 at the Pistons on NBC and Peacock.
Is Boston over the luxury tax?
Yes. Boston's $203.9 million payroll sits above the $200.4 million luxury tax line.
