Houston Texans head coach Gary Kubiak collapsed on the field at the start of halftime Sunday night. He was taken to a hospital, where a team official said he was in stable condition, CNN's Ed Lavander reports.
The 52-year-old coach was walking near the 20-yard line just after halftime started when he slowly bent over and then collapsed.
Late Sunday night, the Texans announced that Kubiak was conscious at a local hospital and that his family was with him.
"All his vital signs are good," said defensive coordinator Wade Phillips, who stepped in as interim head coach. "He did not have a heart attack, but they're still checking on everything with him."
In a post-game news conference, Phillips recalled his confusion in the moments after Kubiak's collapse, describing it as "a shock to everybody."
"I was traveling in and I saw him on the ground and I kept asking, 'What happened?'" he said. "And that's kind of what happened with everybody."
Kubiak was tended to by a flock of medial staff as he lay on the field. He was eventually wheeled out on stretcher.
"We finally got word that they took him to the hospital, but we were unsure of everything," Phillips said.
The Colts went on to win the game 27-24. But Phillips didn't blame the defeat on Kubiak's collapse, saying the Texans had opportunities in the second half.
"When the game was on the line, we didn't play well enough," he said.
But in the end, many were far more concerned about Kubiak than the final score. Colts owner Jim Irsay offered his support to the Texans' coach.
"Big time prayers for Coach Kubiak," Irsay tweeted. "God bless his healthy return and ease his family's worry and concern."
