Veal was placed on the DL a week ago due to soreness in the ulnar collateral ligament in his throwing elbow. The diagnosis came after Veal tossed five innings and allowed three runs in Indianapolis' loss to Gwinnett (Ga.) on May 23.
The Pirates will have a better idea of what sort of recovery process Veal will need and whether surgery will be necessary following the evaluation.
Though Veal was not likely to pitch in the Pirates' rotation this season, he was one of the more intriguing arms in the upper levels of the organization's Minor League system. After pitching sporadically out of Pittsburgh's bullpen in 2009, Veal was being groomed back into a starting role this season.
In nine starts for Indianapolis, Veal went 3-2 with a 4.35 ERA. He had issued 23 walks and struck out 41 in 49 2/3 Triple-A innings.
Veal isn't Indianapolis' first starter to be sent to Andrews this season. Right-hander Kevin Hart met with the noted orthopedist at the beginning of May, after which it was determined that he needed season-ending surgery to repair a torn labrum in his throwing shoulder.
