Matt Harvey will undergo surgery to address thoracic outlet syndrome in his right shoulder, according to Scott Boras.

Dr. Robert Thompson in St. Louis will conduct the surgery, according to the New York Mets.

Harvey's injury involves a constriction of the opening in which nerves and blood vessels pass between the neck and shoulder.

In his second season back from Tommy John surgery, Harvey is 4-10 with a 4.86 ERA in 17 starts.
