Jeremy Hellickson had surgery on his elbow last week and will miss the start of the season according to Marc Topkin of TampaBay.com.
According to the report, Hellickson is expected to be out until at least mid-May.
Hellickson needed arthroscopic surgery after feeling discomfort when he started his off-season throwing program. The procedure is considered minor.
Jake Odorizzi is the most likely candidate to replace Hellickson in the rotation, although you can be sure Andrew Friedman is checking in on cheap free agents and trade targets for a potential replacement.
