The move is retroactive to Aug. 25.
The team called up infielder Dilson Herrera from Double-A Binghamton in a corresponding roster move. Herrera was batting .333 with nine home runs in 60 games for Binghamton.
Murphy has not played since Aug. 24 and said he wanted to avoid the DL, but thought it was in his best interest to get healthy.
"It's frustrating," Murphy said to MLB.com. "I was hoping it wasn't that bad, but it ended up being a little worse than I thought."
Murphy is seventh in the National League with .301 batting average. He also has nine home runs and 53 RBI and leads the NL with 159 hits.
