Broncos assistant head coach Mike Westhoff has resigned. Westhoff, a cancer survivor, cited a health issue in coming out.

Specifically, Westhoff will monitor a health issue that arose last week.

“It is not easy to make this decision, but this was a wake-up call I had to put my health first,” Westhoff said, via Tom Pelissero of NFL Media. “This team is very much headed in the right direction with a solid foundation and a winning culture. I am grateful to Sean for giving me the opportunity to contribute to a first class organization and I wish the Broncos the best.”

Westhoff is a former special teams coordinator. The Broncos’ special teams are currently led by coordinator Ben Kotwica and assistant Chris Banjo.

After various stints in college football dating back to 1974, Westhoff reached the NFL in 1986 with the Dolphins. He remained there until 2000. He worked for the Jets from 2001 to 2012. He retired at that time, returning in 2017 to work with current Broncos coach Sean Payton and the Saints. He stayed through 2018 before joining Payton in Denver last year.

Some will believe the move had something to do with the blocked field goal that cost the Broncos a win in Kansas City on Sunday. As explained by a source with knowledge of the situation, Westhoff would have resigned even if Will Lutz’s field goal attempt late in the loss to the Chiefs had not been blocked. Indeed, Kotwica and Banjo remain Denver’s special teams coaches.
