HOUSTON -- Houston Coach Gary Kubiak was in stable condition late Sunday night after collapsing leaving the field at halftime of the Texans' 27-24 loss to the Indianapolis Colts.
Kubiak hunched over and dropped to his knees at the 24-yard line and was immediately surrounded by medical personnel. He was lifted off the field on a stretcher and taken by gurney to an ambulance.
The Texans didn't say what was wrong with Kubiak but did say he didn't have a heart attack. The team said the 52-year-old coach was conscious as he was taken to the hospital.
"He had an episode, he was lightheaded and dizzy," Texans General Manager Rick Smith said after the game. "He was evaluated by a number of specialists … he is awake and coherent."
Defensive coordinator Wade Phillips took over as coach.
Andrew Luck got off to a slow start before throwing three second-half touchdowns to T.Y. Hilton to overcome an 18-point halftime deficit and give the Colts (6-2) the victory.
Case Keenum threw for 350 yards and three touchdowns but had trouble moving the Houston offense after halftime. The Texans, up 21-3 when Kubiak collapsed, lost their sixth straight.
Houston had a chance to tie it, but Randy Bullock's 55-yard field-goal attempt as time expired sailed wide left.
