Houston coach Gary Kubiak collapsed leaving the field at halftime of the Texans' game Sunday night against Indianapolis and was taken by ambulance to a hospital.
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 cart to the 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 and was with his family as he was taken to the hospital.
Defensive coordinator Wade Phillips took over as coach in the second half.
The Texans led the Colts 24-12 at the end of the third quarter.
Kubiak's collapse came a day after Denver Broncos coach John Fox was hospitalized in North Carolina as he awaits aortic value replacement surgery. The 58-year-old Fox will have surgery in a few days and will miss several weeks while recuperating.
Fox had been told earlier about his heart condition and was hoping to put off the operation until February. As part of his trip to North Carolina over the Broncos' bye week, he met with his cardiologist in Raleigh and was told to seek medical attention immediately if he felt any discomfort. On Saturday, Fox became dizzy playing golf near his offseason home in Charlotte and was taken to a hospital, where tests revealed he couldn't wait any longer to have surgery.
The Colts scored nine points in the third quarter, highlighted by a 10-yard TD pass from Andrew Luck to T.Y. Hilton on a third-and-10 to make it 24-12.
Adam Vinatieri kicked field goals of 30 and 35 yards in the second and third quarters for the Colts, who struggled offensively.
Case Keenum threw three touchdown passes to Andre Johnson for Houston, the last a 5-yarder with 39 seconds left. The TD came after Keenum scrambled 22 yards for a first down.
In the first quarter Keenum, making his second career start, connected on a 62-yard scoring pass to Andre Johnson on the third play of the game, and added a 41-yarder with 4:21 left. It marked the first time since 2010 that Johnson caught two TD passes in a game.
The Colts were playing their first game since losing star receiver Reggie Wayne for the season. Wayne tore his right ACL in an Oct. 20 win over Denver and had surgery.
Texans running back Arian Foster, who missed practice earlier in the week with a hamstring injury, left late in the quarter with a back injury and the team said he wouldn't return.
