The Boston Celtics have added Mitchell Robinson on a three-year, $47.4 million contract that includes a player option in the final year. The move addresses a key need for the team after its first-round playoff exit. It also leaves the New York Knicks without their longtime center.
Robinson, a 7-foot center known for his defensive impact and rebounding, spent his entire career with the Knicks after they drafted him in 2018. He played a major role in their 2025 championship run that ended a 53-year title drought.
The Celtics reached the agreement with the free agent through the mid-level exception. Boston had struggled at center following the departure of Robert Williams III and faced challenges against Joel Embiid in the 2025 playoffs.
New York could not match the offer because owner James Dolan declined to exceed the second apron. The Knicks are now exploring replacements such as Kevon Looney on a minimum deal or potential trades.
Robinson has dealt with multiple ankle surgeries and limited availability in recent seasons. The Celtics plan to manage his minutes carefully during the regular season.
