A raucous atmosphere in Houston got quiet in a hurry, when Texans head coach Gary Kubiak collapsed as the teams were leaving the field at halftime.

There was no immediate word on his condition, but medical personnel were with him quickly, and the 52-year-old coach appeared to be sitting up and speaking. He was then taken off on a stretcher.

The news comes the day after Broncos coach John Fox was hospitalized during his bye weekend because of a heart condition, adding a layer of worry to a concerning scene.

UPDATE 10:15 p.m. ET: Kubiak has been loaded into an ambulance and taken to a nearby hospital.

Defensive coordinator Wade Phillips, who will coach the team in the second half, told NBC’s Michele Tafoya the trip was precautionary.
