He is expected to be out for about eight weeks.
The 23-year-old Taillon has yet to pitch in a major league game.
"We'll see how the recovery goes," general manager Neal Huntington told the Pittsburgh Post-Gazette. "It is two months-ish. I mean, we have been told it is roughly two months until he is ready to compete."
Taillon missed the 2014 season recovering from Tommy John surgery and was set to throw in a minor-league game for the first time since having the elbow surgery in late June before being scratched with lower abdominal pain.
Taillon has not pitched this season after he underwent Tommy John surgery last season, but he has recently been bothered by pain in his lower abdomen.
Taillon was set to make his first minor-league start Tuesday since undergoing Tommy John surgery last year. He had been pitching in extended spring.
"We're working through exactly how long and what the severity is, working through the evaluation process," Pirates general manager Neal Huntington said.
