Capuano, 34, hurt himself covering first base on Tuesday night. He initially stayed in the game but was removed after throwing some warm-up pitches the following inning. Capuano will have an MRI on Thursday and could receive a PRP injection.
Left-hander Ted Lilly made a five-inning minor-league rehab start on Tuesday, so he can presumably step right into Capuano's spot. Lilly agreed to make one more minor-league start after first telling the team he wouldn't accept the assignment. He started the year on the DL with a shoulder issue.
Right-hander Aaron Harang was traded away a little more than a week ago and Zack Greinke is out with a broken collarbone. Capuano had taken Greinke's place in the rotation. Pitching depth, as they say, has a way of disappearing quickly.
The Dodgers have recalled catcher Tim Federowicz to fill Capuano's rotation spot for the time being. He gives the team an extra position player when they head to Baltimore for interleague play this weekend.
