PHILADELPHIA -- Phillies reliever Jose Contreras received a platelet-rich plasma injection to help alleviate pain in his right throwing arm.
It's unknown how much work the Phillies can get out of Contreras going forward. There is no timetable for him to start a throwing program.
"He's got to hold off for a little while," general manager Ruben Amaro Jr. said. "There's some pretty significant soreness just from the injection itself."
Contreras has been on the disabled list since June 20 with a strained right forearm.
