Manager David Bell said Friday that Gibaut (forarm) recently received a cortisone injection after he had "a small tweak" of his calf, Charlie Goldsmith of The Cincinnati Enquirer reports.
The right-hander has been sidelined all season due to forearm issues and underwent anterior interosseous nerve release surgery in May. The calf issue isn't serious and should set him back for only a few days, but it's yet another hurdle in Gibaut's lengthy recovery.
