Gary Kubiak won’t be on the sidelines Thursday night when the Denver Broncos face the San Diego Chargers. The head coach was diagnosed with a “complex migraine condition” and will be on leave from the team for a week.

Kubiak was rushed to the hospital Sunday night after the Broncos 23-16 loss to Atlanta.

Denver GM John Elway said Kubiak has been given the next week off to deal with his condition. Special-teams coordinator Joe DeCamillis will fill in as the team’s interim coach.

“[The doctors] thought the prognosis for him was very, very good and they think that he’s going to spend this week, he’s going to have this week off, he’s going to be back on Monday,” Elway said. “When it comes down to Gary’s health, everybody’s excited about what the prognosis is. We’re just excited Gary’s OK.'”

Kubiak released a statement Monday thanking everyone for their support and says he has full confidence in DeCamillis.

“I’m feeling much better and am thankful for everyone’s thoughts and well-wishes,” Kubiak stated. “It’s tough not being there with our team this week, but I’ve got great confidence in Joe D, our coordinators and coaching staff, and all of our players. I’ll be at home this week resting and getting healthy, and I look forward to rejoining our team on Monday.”

Kubiak, 55, reportedly coached the entire game against Atlanta despite feeling ill before and during the game.

The second-year Denver coach has had prior health concerns. In 2013, while with the Houston Texans, Kubiak reportedly suffered what was described as a mini-stroke during a game against the Indianapolis Colts and spent two days in the hospital.
