Fort suffered a torn ACL during Saturday's preseason contest against the Panthers, Jeremy Fowler of ESPN.com reports.

EDGE Analysis

While it was a clean tear, Fort's season will still likely be over after he undergoes surgery. The nine-year veteran notched a career-high 54 tackles in 14 games with the Ravens last year. In his absence, Malik Harrison and Chris Board will compete for the backup linebacker spot behind Patrick Queen.
