I read today that the injury is fairly minor and he should not be out of action for very long. That is a good thing as he really needs to play in the remaining exhibition games and show what he can do. He apparently wasn't great on Saturday, completing 3 of 9 passes in the first game, though I think he's had a pretty good camp and the coaches obviously like his size and arm. But he needs to show in exhibitions that he can play. With Foles signed as the backup by KC, either Murray or Bray is probably going to be released.
