Manager Torey Lovullo said Saturday that MRI results of Puk's left shoulder revealed that his shoulder capsule hasn't fully healed, Steve Gilbert of MLB.com reports.
Puk has been on the injured list all season while recovering from an internal brace procedure he underwent last summer, as well as a shoulder capsule sprain he suffered while pitching in a rehab game. The results of his latest MRI suggest that Puk's stay on the IL is likely to be extended even further, and he's set to visit Dr. Neal ElAttrache within the next couple of days to receive a second opinion before determining his next steps. An updated timeline for his return could come into focus following his appointment.
