Broncos coach Kubiak announces retirement

Less than 12 months after winning the Super Bowl, Denver Broncos head coach Gary Kubiak has announced his retirement.

It had been reported after Sunday's 24-6 victory over the Oakland Raiders that Kubiak had informed his players of his intention to step down and that was confirmed by the Broncos on Monday.

Denver, having beaten the Carolina Panthers 24-10 last February to claim the Vince Lombardi trophy, failed to make the play-offs this season after winning only nine of their 16 regular season games.

Kubiak insists he is not retiring due to ill health after he suffered a complex migraine that required hospital treatment in October, while he also collapsed during a game while in charge of the Houston Texans back in 2013.

The 55-year-old, who became Denver head coach in January 2015, said: "You've heard a lot about me the last week, but let me just say I'm doing great, I'm okay.

"But coaching is a very demanding business, a tough business. It's been tough and for the first time I've had to tell myself that you can't do that anymore.

"I've struggled big time this year. So this decision is strictly my decision, based on what I've been through this year and how I'm feeling, and I just feel it is time for me to do something different.

"I'm retiring from coaching, I'm getting out of coaching. But I've got a lot to give and I'm going to find something else to do and I'm going to wake up with that same passion as when I was coaching, but it's time to step away from the coaching field."

Kubiak is the latest NFL coach to leave his post in recent weeks after San Francisco fired both general manager Trent Baalke and coach Chip Kelly, while San Diego Chargers coach Mike McCoy was also dismissed after the final regular season game.

Jeff Fisher (Los Angeles Rams), Gus Bradley (Jacksonville Jaguars) and Rex Ryan (Buffalo Bills) were also fired in the past few weeks.
