Caleb Grill is now on the Boston Celtics roster, arriving from free agency as a 26-year-old rookie guard. His contract terms are not on file yet, and Boston already carries a payroll of $201.4 million against a $165.0 million cap.
The move
Caleb Grill is on the Boston Celtics roster as of Monday, Sep 14, according to the club's official roster. The 26-year-old guard arrives from free agency, with no NBA line to his name — he enters as a rookie. No report preceded this move; it was picked up straight from the roster itself, with no advance word from a beat writer or insider on the transaction.
The money
Grill's contract is not on file yet; public salary data can lag a signing by a day, so his cap hit and any years are not announced. Boston carries a payroll of $201.4 million across 16 contracts for 2026-27, over the luxury tax line. The cap sits at $165.0 million, the tax at $200.4 million, the first apron at $209.0 million and the second apron at $221.7 million — the Celtics are already spending above the tax threshold before accounting for Grill's deal.
The fit
Grill has no NBA line from last season. He joins a Celtics backcourt led by Derrick White, who averaged 34.1 minutes and 16.5 points last season, and Payton Pritchard, who put up 32.3 minutes and 17.0 points. Anfernee Simons logged 24.5 minutes and 14.2 points in the same guard rotation. Boston's roster now stands at 21 players, above the standard 15-man limit under the three two-way slots the league allows, and Grill will have to carve out minutes behind that established group.
