KANSAS CITY, Mo. (AP) — The Chiefs are putting kicker Harrison Butker on injured reserve while he undergoes a procedure on his knee, though they hope to have him back for the playoffs, a person familiar with the situation told The Associated Press on Thursday. The Chiefs are expected to sign Spencer Shrader off the Jets' practice squad to fill in for at least the next four weeks, added the person, who spoke on condition of anonymity because the team had yet to announce the roster moves.
