Ethier was on the field playing catch before Friday's game, but he remained out of the lineup as Scott Van Slyke continued to replace him in right field.
Manager Don Mattingly said after talking with team trainer Sue Falsone that the team is going to play it by ear.
"Day to day means day to day with him as far as how he is feeling and if he can go side to side," Mattingly said. "How he progresses depends on him."
Mattingly said the team can't afford to have Ethier come back too soon and then have his recovery take a step backward. If that were the case and it becomes seven or eight days of recovering, a trip to the disabled list might need to be considered.
"We have the days during the All-Star Game, so when he's ready to play, we're all for it," Mattingly said. "But he needs to be ready to play when that happens."
