The team announced the move Tuesday and said Tyrone Taylor will be recalled to fill Yelich's spot in the roster.
Any injury to the 29-year-old is sure to raise concern for Milwaukee considering he already missed time this season with the back injury. Manager Craig Counsell told reporters in April that he "unfortunately hit a bit of a plateau" during his comeback efforts from that initial back injury.
When healthy, Yelich is one of the best players in the league.
The 2018 National League MVP is a three-time Silver Slugger winner and two-time All-Star who also has a Gold Glove and two batting titles on his resume. However, he struggled compared to his other recent efforts during the shortened 2020 campaign and slashed .205/.356/.430.
Yelich has responded with a .353/.463/.382 line through 10 games in 2021.
Despite his struggles at the plate, the Brewers will have difficulty replicating his impact now that he's sidelined once again.
