"There's nothing new, nothing to add," manager Craig Counsell said. "That's what it is. We'll take a couple more days without baseball activities and see where that leaves us."
The move was retroactive to April 14. The Brewers announced Yelich's injury as a lower back strain.
Milwaukee filled Yelich's spot on the roster by recalling right-handed reliever Eric Yardley from the organization's alternate training site in Appleton, Wisconsin.
Yelich, the 2018 NL MVP, is hitting .333 with no home runs and 1 RBI.
"We'll just have to fill in around them until those guys get back. We're not expecting this to be long term,'' Counsell said.
