Sky Sport 24 reports that the 25-year-old spent Thursday morning at the Agostino Gemelli Teaching Hospital, prior to putting pen to paper with the Giallorossi.
Bradley is expected to sign a four-year contract at the Olimpico worth around 800,000 euros a season, with either Leandro Greco, Adrian Stoian or Alessandro Crescenzi heading in the other direction.
The transfer fee for the Chievo midfielder is not yet known.
Bradley joined the Flying Donkeys last summer after a failed spell at Aston Villa and quickly became an integral part of Domenico Di Carlo's plans, as the side finished comfortably in 10th position in Serie A.
