Garza joins a Celtics team moving in an entirely different direction for the 2025-26 season with star Jayson Tatum out for the year with an Achilles injury. Boston moved on from Jrue Holiday and Kristaps Porzingis this offseason and now have brought in Garza.

Garza would likely play the backup role as a third-string center for Boston, pending other moves in free agency.

Free agent center Luka Garza has agreed to a two-year, $5.5 million fully guaranteed deal with the Boston Celtics, sources tell ESPN. The Celtics negotiated the new deal with Garza's representatives Mark Bartelstein and Kieran Piller of @PrioritySports tonight. pic.twitter.com/d5x5HzGYIL
