Eagles defensive assistant Tyler Yelk is leaving the organization after three seasons to join the University of Nebraska as the safeties coach, an NFL source confirmed to Eagles On SI.

Matt Zenitz of CBS Sports was the first to report the coaching move.

Yelk was a college teammate with Nebraska defensive coordinator Rob Aurich at Minnesota-Duluth, where Yelk was an All-American defensive back and finished as the school’s all-time leading tackler.

Yelk arrived to the Eagles as assistant to the head coach in 2023 and was promoted to head coach quality control for Philadelphia’s Super Bowl LIX-winning season in 2024 before being promoted again to defensive assistant last season.

Before landing on Nick Sirianni’s staff, Yelk had coached the safeties at Idaho. 

Other stints included mentoring the safeties and nickel backs at Temple for three seasons where Yelk became familiar with Philadelphia. Nebraska head coach Matt Rhule is a former coach of the Owls but he and Yelk never crossed paths on North Broad Street.

Yelk also had coaching stints at Northern Illinois (safeties), South Dakota (co-defensive coordinator and safeties), Western Illinois (defensive backs, special teams, and co-DC), and UMD (defensive backs/special teams), his alma mater.
