KANSAS CITY, Mo. -- Wide receiver Kyle Williams has been placed on injured reserve by Kansas City with a torn knee ligament.
Williams tweeted about the injury Friday morning just after the team announced it signed receiver Chad Hall to the 53-man roster and placed Williams on IR.
Williams played in 39 games with nine starts in more than three NFL seasons with San Francisco and Kansas City. His only appearance for the Chiefs came in last week's loss to Denver.
It is the second time he has been sidelined with a torn ACL.
Hall has played in 22 games in just over two NFL seasons with the Chiefs and Eagles. He was claimed off waivers on Sept. 1 from the 49ers and played in seven games with Kansas City, making one catch for 9 yards. Hall also returns kicks.
