Turner, 33, was about to begin his fifth season with the Dodgers. Last year, he made his first All-Star team and finished eighth in the National League MVP voting. He finished third in the NL with a .322 batting average. He finished ninth in the NL MVP voting in 2016.
Turner has hit six postseason home runs with the Dodgers, including one that decided Game 1 of the 2017 World Series, and a three-run walk-off blast in Game 2 of the 2017 NLCS. His career postseason batting average is .321.
The injury means the Dodgers will probably have to shuffle their defensive lineup until Turner returns.
