Rams quarterback Sam Bradford may not play on Sunday because of a high ankle sprain that has the second-year player in a walking boot. "I think you are always concerned when you see your quarterback in a boot," St. Louis coach Steve Spagnuolo said. "In my experience with the high ankle sprains, you just never know." Bradford was injured during his team's 24-3 loss at Green Bay on Sunday, and Spagnuolo said he had a noticeable limp when he reported for a team meeting Monday afternoon.
