Manager David Bell said Antone was removed from Tuesday's loss to the Brewers after the right-hander "felt something" in his elbow, Bobby Nightengale of The Cincinnati Enquirer reports.
Antone missed the past two months with a strained forearm and was activated from the injured list earlier Tuesday, only to be lifted after five pitches with the elbow issue. The specifics of the injury remain unclear, but it wouldn't be surprising to see him return to the injured list given he's dealing with another arm problem.
