Cooper was running across the middle, and when he outstretched for a pass, dropped his head and took a nasty hit from the Broncos defense. It resulted in Cooper knocked completely unconscious.

Team officials brought the cart out for Cooper, but he was able to walk off the field with assistance from trainers.

Our thoughts are with Cooper at this time.
