Boston Celtics sign former Knicks center Mitchell Robinson to three‑year deal

Former New York Knicks center Mitchell Robinson, who contributed to the Knicks' 2025 championship run, agreed to a three‑year contract worth $47.4 million with the Boston Celtics. Robinson, drafted 36th overall in 2018, is known for his defensive presence and rebounding, though his free‑throw shooting remains a weakness, pulling down a career‑low .508 percentage.

Robinson's move follows the Knicks' cap‑space constraints that prevented them from retaining him under the NBA's second‑apron limit of $222 million. Boston highlighted his signing on social media, prompting mixed reactions; former teammate Josh Hart posted a rebuke on X, while Robinson expressed regret about leaving New York in comments to fellow player OG Anunoby. The Celtics anticipate Robinson will bolster their frontcourt depth after the Knicks replaced him with veteran Andre Drummond and other roster changes.

The deal marks a notable roster shift in the Eastern Conference, with the Celtics adding a former championship contributor while the Knicks adjust their salary‑cap strategy and roster composition for the upcoming season.
