Braun had been playing for a couple years with a nerve damaged thumb, but had an initial cryotherapy session as soon as the 2014 campaign concluded to help fix the issue.
At first, it seemed like the Brewers had called outfielder Shane Peterson up to balance the roster a bit with no true fourth outfielders on the bench. Instead, Peterson will be needed to start for a few days as Ryan Braun has left the team to have another cryotherapy procedure on his thumb, reports Todd Rosiak.
Braun isn't expected to miss much time, as manager Craig Counsell says this is more 'maintenance' on the thumb than anything.
