Texans coach Gary Kubiak collapses on sideline

(UPI) -- Houston Texans head coach Gary Kubiak collapsed on the sidelines Sunday as he was walking off the field at halftime during the game against the Indianapolis Colts.

Kubiak was transported to a hospital, and assistant coaches, led by Wade Phillips, took over for the rest of the game.

Kubiak's hospitalization was mainly a precautionary measure, and the Texans say he did not lose consciousness or have a heart attack.

Update: Coach Kubiak has been taken to a local hospital, he is conscious and his family is with him. #TexansGameday

"He had an episode; he was light-headed and dizzy," Houston general manager Rick Smith said after the game. "He was evaluated by a number of specialists … he is awake and coherent.

He has no known related medical problems.

"We have to assess … obviously, there's a lot of info," Smith said. "Hopefully, Gary will be back with us tomorrow."

The team ended up losing 27-24 against the Colts despite being up at halftime. They attributed the loss to being concerned about Kubiak's health.

Colts coach Jim Irsay tweeted his support for Kubiak after the game.

Big time prayers for Coach Kubiak...God bless his healthy return and ease his family's worry and concern.
