Ford (knee) was placed on injured reserve Thursday, Josh Weinfuss of ESPN.com reports.
Ford has missed the last two games with the knee injury, and the issue will end up being a season-ending one. Ford had not played a single defensive snap his rookie season and was used primarily on special teams.
Ford went from a limited workload Thursday to a non-participant at Friday's practice, so he appears to be trending in the wrong direction. If the 23-year-old is unable to go look for Harlan Miller to step in as Tyrann Mathieu's primary backup at free safety.
Ford (finger/hamstring) logged a full practice Tuesday.
After a being a limited participant Monday, it looked like Ford's status for Thursday's game against the Seahawks could be up in the air. However, his full participation Tuesday indicates he is on track to play Week 10.
