"It's a bad tear," Crawford told reporters, according to Dylan Hernandez of the Los Angeles Times.
Outfielder Enrique Hernandez has been called up from Triple A to replace Crawford on the roster and is in the starting lineup for Tuesday night's game.
Crawford, 33, is batting .245 this season and has started 13 of the Dodgers' 19 games in leftfield.
Crawford hit a triple in the second inning of Monday's game agaist the San Francisco Giants and appeared to wince after sliding into third base.
He remained in the game to play defense in the top of the third inning but was replaced by a pinch hitter in the bottom of the third.
Speaking with reporters Monday night, Dodgers manager Don Mattingly hinted that Crawford's injury could create an opportunity for rookie Alex Guerrero to see more playing time. "We're going to have to find at-bats for Alex the way he is swinging," Mattingly said, according to the Times. Guerrero has 11 hits in 22 at-bats this season.
