Dee Ford‘s back injury has become serious enough the Chiefs placed the outside linebacker on IR. The team announced the move and the signing of Eagles practice squad cog Justin Hamilton, a defensive tackle, to the 53-man roster. Ford had missed the past four Chiefs games with the back ailment. He is signed through the 2018 season via fifth-year option. The Chiefs exercised Ford’s guaranteed-against-injury option of $8.72MM back in May. However, Ford did not have the kind of year he did when he broke out in 2016. He will finish his season with just two sacks and six games played. The 2014 first-round pick registered 10 last season, emerging after two years largely spent sitting behind Justin Houston and Tamba Hali.
