Mike Westhoff, the Denver Broncos' assistant head coach, has stepped down due to health concerns, specifically vision issues, as reported by NFL Media and other sources. The 76-year-old coach experienced blurred vision last week and, following medical tests including an MRI, decided to prioritize his health. Westhoff, a renowned special teams coach with a 46-year career, thanked head coach Sean Payton for the opportunity to contribute to the Broncos' success. Despite the Broncos' recent loss to the Kansas City Chiefs, Westhoff expressed confidence in the team's direction and wished them well. His resignation comes as the Broncos aim for playoff contention with a 5-5 record, continuing under the guidance of special teams coordinator Ben Kotwica.
