The slugger has been getting daily treatment, but has played a full game only three times since suffering the injury on May 1, when he collided with first-base umpire Tony Randazzo as he turned to chase a double down the line by Rockies outfielder Carlos Gonzalez.
"It just seems to keep going on," manager Don Mattingly said before Sunday's series finale against the Marlins. "We're trying to get on the other side of this thing."
Scott Van Slyke, promoted from Triple-A Albuquerque on Friday, started at first base in place of Gonzalez and hit fifth.
Gonzalez leads the Dodgers with a .345 average and 26 RBIs. He leads the National League with a .500 average (14-for-28) with runners in scoring position.
