Feyereisen (biceps) felt good following Tuesday's rehab appearance at Triple-A Durham, Steve Carney of Sports Radio 620 WDAE reports.
Feyereisen has allowed three runs on three hits and a walk in 1.2 innings across his last two rehab appearances. However, manager Kevin Cash said Wednesday that the 28-year-old reported feeling good after his most recent outing, and he could return during the Rays' weekend series in Baltimore.
