Crawford had been sidelined since April 28 because of a strained right forearm. He lost feeling near his elbow after making a relay throw to third base and was placed on the DL the following day.
A left-handed hitter, Crawford was not in the lineup against the Cubs on Wednesday. Left-hander Jose Quintana started for Chicago.
Crawford was batting .188 with two homers and six RBI. To make room for him, the Phillies optioned infielder Mitch Walding -- who struck out in all six plate appearances following his promotion last week -- back to Triple-A Lehigh Valley.
