Broncos rookie cornerback Parrish Cox suffered a head injury in the third quarter of the team's loss to the Raiders on Sunday. Cox couldn't recall any of the details from the game. He clearly remembers the night before and then coming to in the trainer's room. "I woke up and asked what the score was and they told me, 'A lot to a little,' " Cox said. "That was kind of shocking to me -- I don't remember nothing."
