Updated Monday: The team says Kubiak is coherent and recovering but will stay in the hospital at least another 24 hours.
"Our primary concern is of course with Gary's health and well-being," Texans Executive VP of Football Operations and General Manager Rick Smith said. "There have been so many people throughout the city and across the country that have reached out to express their love and support and we are thankful for everyone's thoughts and prayers. Gary is alert, coherent and in good spirits. He is continuing to be evaluated and monitored."
Update Sunday night: Texans general manager Rick Smith told NBC after the game Kubiak "had an episode" where he was lightheaded and dizzy, but his vital signs are stable, and Kubiak is responsive in the hospital, and might return to work as soon as Monday.

Just as Texan fans began to celebrate a fantastic first half against the Indianapolis Colts tonight, things got real serious real fast when head coach Gary Kubiak collapsed as he headed to the locker room.
NBC reported that Kubiak looked to be in great pain, his eyes closed, as he was attended to by personnel. He was speaking, though, so he was conscious.
Kubiak was taken off the field on a stretcher and transported to a nearby hospital. Coach Wade Phillips, who took over for Kubiak, told NBC that the hospitalization was a "precautionary move," which again sounds hopeful. His family was with him.
Earlier this week another NFL coach, Denver's John Fox, collapsed on a golf course and had to be taken to the hospital.
