Bart (thumb) was placed on the 10-day injured list Tuesday, Kevin Gorman of TribLive.com reports.
The 27-year-old was lifted from Sunday's matchup against Atlanta due to the injury and will now be sidelined for at least the next week and a half, though the severity of the injury remains unclear. Grant Koch was called up from Triple-A Indianapolis and will serve as Yasmani Grandal's backup while Bart is unavailable.
