Gibaut (forearm) did not make a scheduled appearance for Triple-A Louisville on Wednesday in order to be further evaluated, Mark Sheldon of MLB.com reports.

EDGE Analysis

Gibaut had thrown 25 pitches in a rehab appearance Tuesday and was scheduled to pitch again the next day. The Reds had targeted April 20 as a return for the right-hander, but manager David Bell said it will likely take longer now. The team will know more after Gibaut visits a doctor, and the pitcher could have his rehab assignment paused.
