The health of Sam Bradford's surgically repaired knee is something the Minnesota Vikings are monitoring, but it won't keep him sidelined for Sunday's game against the Pittsburgh Steelers. Bradford, fresh off an impressive performance in the Vikings' season-opening win over the New Orleans Saints, is listed as questionable for Sunday after being limited in practice all week because of a knee injury. Despite the designation, Vikings coach Mike Zimmer told reporters Friday he anticipates Bradford will start this weekend. NFL Network Insider Ian Rapoport provided some clarity on Bradford's situation during NFL Total Access on Friday: "It doesn't sound like they're too concerned with Sam Bradford," Rapoport reported. "He's a little banged up. Had an MRI, had some tests. It did not reveal any structural damage, but the problem is he's had a lot of structural damage on that knee, so the actually MRI and what they found may be hard to decipher. Of course, he's had two [torn] ACLs. But they do think Sam Bradford is going to be on the field and playing, this just might be something he needs to kind of work with and deal with some maintenance on over the next couple weeks." ESPN first reported Bradford underwent an MRI.
