General manager Ruben Amaro Jr. on Wednesday said an MRI revealed a mild to moderate strain of Rollins' right calf. Amaro says he hopes it will take two to four weeks for Rollins to recover.
Rollins, the 2007 NL MVP, was injured during warmups before Monday's home opener against the Washington Nationals. The 31-year-old three-time All-Star was off to a hot start, hitting .391 and scoring eight runs in seven games.
Amaro says the team will be cautious so Rollins is fully healed when he returns.
Rollins' stint on the disabled list is retroactive to April 13. To replace him on the 25-man roster, the Phillies called up Wilson Valdez from Triple-A Lehigh Valley.
