BALTIMORE -- Dodgers pitcher Chris Capuano had an MRI and platelet-rich plasma injection Thursday in his injured calf muscle, the club announced.
Capuano left Tuesday night's game with a strained left calf muscle, which he said he originally felt stretching before last Thursday's game in San Diego.
That was the game that left Zack Greinke with a broken collarbone because of a benches-clearing fight. Capuano said his calf worsened sprinting from the bullpen to the infield during the brawl.
Capuano, who opened the season in the bullpen, took four days of treatment and believed he was healthy enough to take Greinke's start, but was injured in the second inning covering first base and placed on the 15-day disabled list.
Capuano did not accompany the club to Baltimore, and manager Don Mattingly said he did not know if Capuano would join the club in New York next week.
