Rapport has said that Brady is still expected to play and should be able to work himself into health as we get closer to Sunday. I feel like if this was a major injury the national media would be all over it with exhausting coverage, so far it has just been a side story on every major site (ESPN, SI, CBS Sports, etc). If this was truly something major wouldn't they be splashing it as the above the fold center headline? The lead story on ESPN is about Austin Rivers currently. Brady isn't even mentioned anywhere on the main page currently.
Hopefully this is just a blip and they're being cautious and we'll laugh about the angst after Brady and company lift another trophy in two and half weeks.
