ENGLEWOOD, Colo. – In his first media appearance back at UCHealth Training Center since missing a week to recover from a complex migraine condition, Head Coach Gary Kubiak said he was feeling "really good."

"Had too much rest, unfortunately," he said. "I didn't want it, but I got it. I feel very good."

Since the night of Oct. 9, when Kubiak left Sports Authority Field at Mile High in an ambulance as a precaution, he had been resting and recovering away from the team. And after talking with doctors in both Denver and Houston last week, Kubiak said he's "very encouraged" and that all his tests came back "great." The doctors have worked with Kubiak to help him sleep better by improving his sleep patterns and habits.

"I feel very comfortable with where I'm headed and how I'm feeling," Kubiak said.

Kubiak said his doctors in Houston and Denver collaborated during the week to "discuss what happened both times," a reference to a 2013 scare when he collapsed at halftime while head coach of the Houston Texans.

"It was different for me," Kubiak said. "They were different to me. They've obviously had some conversations trying to discuss what happened both times. But to me they were different. Like I said, I feel very good."

Kubiak said he told Head Athletic Trainer Steve 'Greek' Antonopulos on Oct. 9 that he hadn't been feeling 100 percent, but Kubiak also said that he'd "coached football games not feeling good before." Kubiak said he thought the feeling was flu-related and that he hadn't felt 100 percent since Saturday evening and also woke up Sunday morning feeling ill.

After a week of rest in which he had very little contact with the team, Kubiak said he's more than ready to be back to work.

"It just makes you really appreciate what you're doing," he said. "We're in a business where you go, go and go. You've got 16 weeks to be as good as you can be -- and all of a sudden taking two days away from here? When you're a football coach, taking two days away from what you do is like, 'What the hell is going on here?' It's like having a summer off or something.

"It just makes you appreciate the players, makes you appreciate being around the coaches, the players, even [the media]."
