Gary Kubiak is expected to step down as head coach of the Denver Broncos due to health concerns.

Denver hired Kubiak just two seasons ago as he replaced John Fox. 

Kubiak left the team for a week in October and missed a Thursday night game in San Diego for what the team called a "complex migraine condition." Back in 2013, when Kubiak was coaching the Houston Texans, he suffered a mini-stroke during a game and had to be rushed to the hospital.
