The Phillies transferred Turnbull (lat) from the 15-day injured list to the 60-day IL on Saturday.
The move makes room on the 40-man roster for Tyler Gilbert, whose contract was selected from Triple-A Lehigh Valley. Turnbull landed on the 15-day injured list June 27 due to a right lat strain, and his move to the 60-day IL confirms that he won't be ready for activation until at least the final week of August. Whenever he eventually rejoins the big club, Turnbull is expected to work out of the bullpen for the remainder of the season. He has been limited to bullpen sessions since the start of August and has yet to embark on a minor-league rehab assignment.
