Broncos head coach Gary Kubiak taken to hospital after game Sunday night

DENVER -- The head coach of the Denver Broncos was taken to the hospital after the game against the Atlanta Falcons Sunday night.

Gary Kubiak had flu-like symptoms, according to Patrick Smyth with the Broncos.

Smyth said Kubiak was being evaluated "as a precaution."

"In his second season as Broncos head coach, Kubiak has paid strict attention to his health since he suffered a transient ischemic attack -- often called a "mini-stroke" -- during a Nov. 3, 2013 game while he was the Houston Texans' head coach," officials said on the team website.

Kubiak collapsed on the Reliant Stadium sideline during halftime at the 2013 game.

“You never want to see a family member go down on national TV,” his son Klint Kubiak said at the time. “It was an incredibly scary deal.”

"The official diagnosis [was] that Kubiak suffered a TIA, or transient ischemic attack, which occurs when a blood clot blocks an artery for a short time and affects blood flow in the brain," the NFL reported.

Gary Kubiak's treatment after the attack as well as what caused it are details that have never been made public, and Klint Kubiak didn’t want to divulge those details. He said his dad made one concession: He was burned out.

Kubiak was dismissed by the Texans following the 2013 season but accepted an offer to become the offensive coordinator with the Baltimore Ravens about a month later.

Kubiak signed a four-year deal to become the head coach of the Broncos in Jan. 2015, after general manager John Elway dismissed head coach John Fox.
