The Brewers are not expected to have catcher Stephen Vogt for Opening Day after a second opinion on his ailing right shoulder revealed a strained capsule.
Vogt, 33, will be shut down indefinitely.
"We're basically going to have to slow everything down," Brewers manager Craig Counsell told reporters. "It was not a new diagnosis. We're just going to have to go a little slower. We've got to get him pain-free before he can start throwing."
Acquired from the Athletics last season, Vogt went on to hit .254 with eight HRs in 122 at bats for Milwaukee.
