Bradford sat out the Vikings' Week 2 loss to the Steelers with a sore knee, but Zimmer told reporters the veteran "felt better [Monday], so we'll just see how he's doing as we move forward day to day," per the Tampa Bay Times. Bradford said he's done a lot of work to get swelling out/controlled, NFL Network's Tom Peliserro reported.
When asked what he's evaluating to decide if can play Sunday, Bradford said if he can't perform in practice, he likely won't play. He was limited in practice on Wednesday, according to the team's injury report. "You've got to be able to play quarterback," the quarterback said.
Bradford added: "A lot of it just depends on how my knee responds when we go out there and practice this week."
Bradford underwent an MRI after a fascinating performance in Week 1, but tests were difficult to read because the quarterback -- following two ACL tears -- has so much scar tissue from those injuries, per NFL Network Insider Ian Rapoport.
The hope was that Bradford would only miss a week of play, but his status remains a situation to monitor as we creep closer to Sunday.
