Williams (knee) returned to practice earlier this week, Herbie Teope of The Kansas City Star reports.
The running back has rejoined his teammates after missing a day or two with a minor knee injury. Williams is trying to lock down KC's No. 2 spot at running back, fending off competition from Jerick McKinnon and Darwin Thompson. Given his value on passing downs and special teams, Williams is a safe bet to make the Week 1 roster even if the Chiefs are more inclined to use another running back for carries off the bench behind Clyde Edwards-Helaire.
