Emotions at Sports Authority Field at Mile High went from an extreme high to an extreme low in a matter of seconds on Sunday.

First, Broncos cornerback Bradley Roby intercepted Philip Rivers for a 51-yard touchdown to give the Broncos a 10-7 lead in the second quarter.

But on the play Chargers running back Melvin Gordon collided with Broncos defensive coordinator Wade Phillips, sending the 69-year-old crashing to the ground.

Phillips stayed on the ground and had to be removed from the field on a stretcher, although he appeared to be moving his fingers with his eyes open.

He was immediately taken to a hospital, per CBS Sports.

UPDATE: Phillips out of hospital, will return to Broncos on Monday

It was a scary moment for a team who were without their head coach, Gary Kubiak, the last time they faced San Diego. Kubiak took the game off after being hospitalized five days prior with a complex migraine.

Here’s what Twitter was saying as Phillips was being attended to on the Denver sideline.
