HOUSTON — Houston coach Gary Kubiak collapsed at halftime and was taken by ambulance to a hospital, a chilling blow for the reeling Texans after their best start in months.
Up 21-3 when Kubiak went down leaving the field at the break, the Texans unraveled in the second half, falling 27-24 to the Indianapolis Colts for their sixth straight loss after opening the season 2-0 with Super Bowl hopes.
"We were all very worried," quarterback Case Keenum said. "When we went back out they told us he was ... stable. We were all upset about that but trying to stay focused at the same time."
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 the ambulance.
The Texans didn't say what was wrong with Kubiak but did say he didn't have a heart attack, and he was in stable condition. The team said the 52-year-old coach was conscious and was with his family as he was taken to the hospital.
"He had an episode, he was light-headed and dizzy," Texans general manager Rick Smith told NBC after the game. "He was evaluated by a number of specialists ... he is awake and coherent.
"He went to a knee, and they laid him on the ground. He is stable; for precautionary reasons we wanted to get him to the hospital. We have to assess ... obviously, there's a lot of info. Hopefully, Gary will be back with us tomorrow."
Andrew Luck rallied the AFC-South-leading Colts (6-2), throwing three second-half touchdown passes to T.Y. Hilton. Luck has 10 game-winning drives in the fourth quarter or overtime, the most in a quarterback's first two seasons since 1970.
