The Buccaneers have ruled out Winfield (ribs) for Thursday's game against the Cowboys.
Analysis:Per Jenna Laine of ESPN.com, Winfield is expected to miss 2-to-4 weeks due to a "slight rib fracture" that he sustained during the Buccaneers' loss to the Packers this past Sunday. It's unclear whether he needs a stint on IR, but for as long as he's sidelined, Ifeatu Melifonwu figures to start alongside Tykee Smith at safety.
