Matt Shoemaker's rehabilitation from a forearm strain ground to a halt on Sunday when the right-hander was shut down indefinitely because of discomfort in the nerve that was surgically repaired last August.
Shoemaker, who made only 14 starts last season because of a radial nerve compression in the forearm, aggravated the injury in his first regular-season start this season and has been sidelined since.
While an electromyogram (EMG) test on Monday "showed some degree of improved healing in the area," according to general manager Billy Eppler, the issue is clearly not resolved. Shoemaker will travel to Missouri next week to be examined by a peripheral nerve specialist.
