OAKLAND, Calif. — The Golden State Warriors have completed the trade sending two-time All-Star forward David Lee to the Boston Celtics for Gerald Wallace and Chris Babb, the teams said Monday.

They agreed to the trade July 7, but Boston needed time to sort out other moves in free agency before acquiring Lee.

“We are excited to welcome David as a member of the Celtics family,” Celtics general manager Danny Ainge said in a statement. “His proven skill set and experience on a championship team will add valuable depth to our frontcourt and a veteran presence to our locker room.”

Lee was an All-Star in 2010 with New York and 2013 with Golden State. But he injured his left hamstring in the final preseason game in October and his role diminished with the emergence of Draymond Green, the runner-up for defensive player of the year.

Lee played the fewest minutes of his career and averaged just 7.9 points per game last season for the NBA champion Warriors, who were looking to trade Lee to limit the team’s luxury tax hit next season. Lee is due about $15.4 million in the final year of his contract.
