The Warriors announced the deal Thursday and planned to formally introduce Jerebko on Monday.
A native of Sweden, Jerebko has played nine NBA seasons with Utah, Boston and Detroit. In 32 postseason games -- four starts -- for the Jazz and Celtics, he has averaged 4.0 points and 3.1 rebounds.
Golden State had already added center DeMarcus Cousins in free agency and re-signed two-time reigning finals MVP Kevin Durant and forward/center Kevon Looney after winning a second straight title and third in four years. Centers JaVale McGee (Lakers) and Zaza Pachulia (Pistons) have departed.
