Ian Rapoport of NFL Media reports that Vikings QB Sam Bradford is still experiencing knee pain and it doesn’t sound like he’s going to be ready anytime soon. According to Rapoport, there’s still no timeline for Bradford’s return to the Vikings. As for Teddy Bridgewater, Rapoport says that he’s healthy enough for the Vikings to officially activate him off of the PUP list after their bye week and then have him compete for the starting job with Case Keenum. Rapoport adds that he wouldn’t be surprised if Bridgewater was under center for the Vikings at some point in the near future. The Vikings have a three-week window to officially add Bridgewater to their active roster. A few weeks ago, Jay Glazer of FOX Sports reported that Bradford’s knee is “much worse than people know.” According to Glazer, Bradford’s knee has so much wear and tear and cartilage issues built up over the years that caused constant pain and swelling. As of now, Bradford doesn’t view this a career-ending situation, but Glazer says that if his knee continues to swell up and continues to cause him pain, “Bradford is going to have to look at that knee and make a decision on his career.” Rapoport previously reported that Bradford is still an experiencing pain in his knee, which led to him traveling to New York this past week to begin Regenokine treatments in hopes of getting the inflammation out of his knee. According to Rapoport, these treatments involve drawing Bradford’s blood, spinning it down and then reinjecting it into the knee over five or six days.
