Manager Pat Murphy confirmed Thursday that Priester will begin the season on the injured list due to a nerve issue in the thoracic outlet syndrome family that causes pain in his right wrist, Adam McCalvy of MLB.com reports.
Priester visited a vascular specialist Wednesday in Dallas, where he was diagnosed as having the nerve issue in the TOS family. It is believed he'll be able to treat the injury without going through surgery. Priester threw lightly Thursday and is scheduled for a bullpen March 21. While he will miss the beginning of the season, it's unclear exactly how long he's expected to be sidelined.
