The move was made retroactive to Saturday. The team also recalled right-hander Evan Phillips from Triple-A Norfolk.
Before the move was announced, Orioles manager Brandon Hyde told reporters that the first baseman "has been sore for a few days."
Davis, 33, is hitting just .171 this season with five home runs and 17 RBIs.
He began the season by setting a major league record with an 0-for-54 streak that dated back to last September before he got his first hit in mid-April.
He appeared to be on the rebound after snapping that streak before slumping again recently. He hasn't started a game for the Orioles since Thursday against the New York Yankees.
