There's a bit of a mind game here. The more unclear it is who is going to play, the more players you have to prepare for.
Limited in practice means less than 100% of the practice. That means if they hold you out the last five minutes you're limited. I am curious of both Kuper and Woodyard's status this game. If both play, it was all precautionary. If not, the injury is more serious than they thought.
