Broncos defensive coordinator Wade Phillips collapsed on the Denver sideline after being hit by a player during Sunday's game against visiting San Diego. Chargers running back Melvin Gordon was chasing the ball on a Philip Rivers interception and ran into Phillips. The Broncos defensive coordinator appeared to strike his head hard against the ground, just behind where the team was standing.

Phillips remained on the ground for a lengthy amount of time while being attended to by medical personnel. He would later be taken to the hospital but was released on Sunday evening.

His head appeared to strike the ground after falling backwards when Gordon hit him at full speed.

"Saw his eyes open, he was answering questions from the team's medical staff as they load him on the cart they will take him immediately off the field," CBS Sports Jamie Erdhal reported.

Both of Phillips' hands were moving as he was wheeled off the field.

Reggie Herring is now calling plays for Denver, who leads the Chargers 10-7 in the second quarter. ( Follow the game here.)

Phillips won't likely return and per Erdhal is headed to the hospital for additional testing but is awake and alert.

The Broncos confirmed that Phillips is alert/awake and has feeling in his extremities, but will go to the hospital for testing.
