Bukauskas underwent an MRI on his right arm after suffering an injury during a live batting practice session Wednesday, Adam McCalvy of MLB.com reports.
McCalvy is referring to the injury as a "setback," which could indicate Bukauskas is again having issues with his right triceps, which is an injury that sidelined him for a bit last season. He's in Brewers camp as a non-roster invitee, and this development could erase any chance he might have had to make the Opening Day roster.
