Hollands had a torn common flexor tendon. He tried to rehab from the injury once, but it caused him problems again in Spring Training.
The Phillies also announced right-handers Miguel Alfredo Gonzalez and Ethan Martin had MRI exams and both revealed inflammation in their right shoulders.
The Phillies said both will not throw for the next two to three weeks before being re-evaluated. Gonzalez is in the second year of a three-year, $12 million contract. He originally agreed to a six-year, $48 million contract in July 2013, but the Phillies renegotiated the deal because of concerns about his arm following his physical.
Those concerns have been more than deserved. Gonzalez, 28, opened last season on the 60-day disabled list because of a right shoulder injury.
Martin, 25, also missed time last season because of a shoulder injury.
