Dodgers starter Tyler Glasnow was transferred to the 60-day injured list Saturday, another sign that his balky back is hindering his rehab progression.

The 32-year-old right-hander has been out since May 8, two days after a back spasm surfaced. Initially, the team expected him to miss a short period of time.

Instead, Glasnow was shut down and manager Dave Roberts said the pitcher still hasn't been cleared to resume a throwing program.
