He will have treatment through the weekend and be reevaluated next week
If Crawford is unable to return by the Oct. 1 season finale and the Giants don't rally to earn a wild-card berth, the three-time All-Star's 13-season run with San Francisco could be over.
The Giants are three games out of the final National League wild-card spot with 9 games to play, six of which are against the Dodgers.
Crawford is batting a career-worst .197 with seven home runs and 38 RBIs in 93 games while playing the final season of a two-year, $32 million extension he signed in August 2021.
A two-time World Series champion and four-time Gold Glove winner, Crawford is a career .250 hitter with 146 home runs and 744 RBIs in 1,654 games since making his MLB debut with the Giants in 2011.
Also Thursday, San Francisco called up right-hander Tristan Beck, infielder Marco Luciano and infielder/outfielder Tyler Fitzgerald from Triple-A Sacramento.
