The Ravens are in need of a quarterback after Robert Griffin III suffered a hairline fracture in his right thumb and is expected to be out four to eight weeks.
With that, the team is expected to ink former Green Bay Packers backup QB Joe Callahan.
With RG3 sidelined, the #Ravens are expected to sign QB Joe Callahan, pending a physical, source says. Former #Packers backup saw action with the #Eagles last preseason. Baltimore OC Greg Roman coached Callahan in ‘08 at Holy Spirit HS.
