Chad Billingsley could sit out all of the 2013 season if he has to undergo surgery to repair a partially torn ligament in his right elbow.
Billingsley, who had developed into a reliable No. 2 pitcher behind ace Clayton Kershaw, will not pitch again this season, no matter how far the Dodgers might advance should they qualify for the postseason.
The Dodgers first will try a rehabilitation program, allowing the right-hander four to six weeks of rest and treatment before he resumes throwing. Billingsley said he has a slightly torn ulnar collateral ligament, which often requires Tommy John surgery.
"It makes you cringe a little bit," Billingsley said, "but they say I have a chance to heal from it before I have to worry about getting cut."
