Chiefs Place Two Young Prospects on Injured Reserve After Camp Injuries

The moves strip Kansas City of developing depth at edge as well as tight end, forcing quick roster work to fill two open offseason spots.

Overview

  • Ethan Downs tore his left ACL during the Chiefs’ opening training-camp practice on Tuesday, and the team confirmed he was placed on injured reserve and will miss the 2026 season.
  • Rookie tight end John Michael Gyllenborg was also moved to injured reserve after testing showed a knee injury that ends his rookie year, a decision the team reached after further evaluation.
  • Both placements free two spots on the Chiefs’ 90-man offseason roster and have prompted the club to schedule tryouts and rep internal candidates to plug immediate depth needs.
  • Downs had worked up from the practice squad after joining Kansas City late in 2025 and was viewed as a special-teams asset, while Gyllenborg is a Kansas City local who had been competing to back up Travis Kelce.
  • Expect increased reps for practice-squad holdovers and undrafted players such as Tyreke Smith, VJ Andreson, Anthony Dunn and Mason Pline, and note that media coverage has speculated about low-cost veteran edge options as a possibility but not a confirmed plan.
