Coach Jay Gruden said Friday that Williams didn't need an MRI, as had been anticipated, and that the knee was stable.
Williams was injured in Thursday night's 45-14 loss.
Backup safety Trenton Robinson left the game in the fourth quarter with a high ankle sprain and could miss several weeks. Gruden said Robinson was on crutches Friday.
Tight end Niles Paul is recovering from a concussion from a helmet-to-helmet hit in the game. He'll have to go through the NFL-mandated concussion protocol before he can return.
Gruden said defensive end Jarvis Jenkins is day-to-day. Jenkins left the game with a rib injury.
