Greinke isn't sure if he'll be ready for the start of the season. (USATSI)

Zack Greinke was diagnosed with inflammation in the back of his right elbow on Monday, and although he is expected to rest only 2-3 days before starting a throwing program, the Dodgers right-hander isn't sure if he'll be ready in time for the start of the season.

Greinke, 29, was scheduled to start the second game of the season for Los Angeles since Clayton Kershaw is getting the nod on opening day. The Dodgers signed Greinke to a seven-year, $157 million contract this winter after he went 15-5 with a 3.48 ERA for the Brewers and Angels in 2012.

If Greinke is unable to start the season on time, the Dodgers have plenty of rotation depth at their disposal. In addition to Kershaw they have righties Chad Billingsley, Josh Beckett and Aaron Harang, as well as lefties Hyun-Jin Ryu, Ted Lilly and Chris Capuano. One or two could be traded before the season even if Greinke will start the year on the DL.
