Broncos All-Pro cornerback Pat Surtain II suffered a concussion in the first quarter Sunday against the Los Angeles Chargers and will not return to the game. Surtain had tight coverage on Chargers receiver Ladd McConkey and broke up a pass, but hit his head on the turf as they rolled over. Surtain stayed on the ground for a couple of minutes while being attended to by medical staff. He was then able to get up and jog off the field on his own, but he had his hands raised up and holding his helmet as he made his way off the field.
