As the Chargers tried to find a way to get back into their playoff game at Denver, they became shorthanded in the secondary.
Defensive back Marcus Gilchrist exited with an apparent concussion, after taking the helmet of a teammate to his own helmet.
Gilchrist was obviously dazed, and it took several minutes for him to be ready to walk off the field.
In the first half, linebacker Manti Te’o suffered a concussion after being struck by a teammate. Te’o did not return.
Meanwhile, the Broncos have answered San Diego’s only touchdown with another touchdown, pushing the lead to 24-7 with 8:12 to play.
