LOS ANGELES -- Injured Dodgers pitcher Chad Billingsley received a platelet-rich plasma injection on Tuesday for elbow tendinitis.
Billingsley, who is returning from April 2013 Tommy John surgery, had a setback in his first Minor League rehab start that originally was attributed to scar tissue. Continued tightness was diagnosed as tendinitis of the flexor tendon.
Billingsley said he will be shut down for five to seven days and then resume a throwing program, but he didn't know how much longer his recovery is now expected to take.
