The Reds transferred Gibaut (forearm) from the 15-day injured list to the 60-day IL on Tuesday.
Gibaut was shut down from throwing late in April due to lingering issues with his strained right forearm and has now been put on the 60-day IL. He's consistently had his timetable for return pushed back after it was once believed he'd have a chance to be ready for Opening Day. He's still eligible to return in late May but may not be healthy by that point.
