49ers Rookie Mikail Kamara Suffers Season-Ending Torn ACL

The injury heightens short-term strain on San Francisco’s thin edge rotation, narrowing roster options.

Overview

  • The 49ers confirmed Monday that rookie defensive lineman Mikail Kamara sustained a torn ACL and will miss the 2026 season.
  • San Francisco placed Kamara on a waive/injured designation, and he is expected to revert to the team's injured reserve list if he clears waivers.
  • General Manager John Lynch previously said wide receiver Ricky Pearsall will undergo season-ending PCL surgery, adding to the team's growing training-camp injury list.
  • Practice reports after Kamara’s injury showed multiple absences and limitations, with players such as Romello Height, Cam Sample and Mykel Williams unavailable or limited and Nick Bosa working restricted drills.
  • The timing of Kamara’s tear compresses the club’s ability to evaluate edge depth and could lead the 49ers to add experienced linemen or shift existing roster spots before preseason games.
