Brown's "degenerative knee condition," head coach Mike Vrabel dismissed the notion that the team is concerned about the 29-year-old's health. … We're very confident in where he's at physically," Vrabel told reporters on Monday. "It's a factor, but we examined him," Wolf told Epstein. Our training staff and medical staff signed off on it." Vrabel added that he and the Patriots' training staff are satisfied with what they've seen from Brown since his arrival.
