The Chiefs announced that they have placed cornerback Phillip Gaines on injured reserve. This means that Gaines will not be in action for Saturday’s Wild Card game against the Titans or any other potential playoff games. 
Gaines saw a good amount of time to start the season, but slipped on the depth chart as the season wore on. He did see an uptick in playing time in Week 17, but the Chiefs are not willing to keep him on the roster while they wait to see how his elbow heals. Without Gaines, the Chiefs will move forward with Marcus Peters, Terrance Mitchell, Steven Nelson, and Darrelle Revis, Keith Reaser, and Kenneth Acker as their cornerbacks.
To take Gaines’ place on the roster, the Chiefs have signed defensive tackle Stefan Charles. Charles did not see the field in 2017 after missing the Jaguars’ initial cut, but he was a regular for the Bills and Lions over the previous four seasons.
