Kansas City, MO (My Sportsbook) - Dallas Cowboys running back Felix Jones and wide receiver Roy Williams are out for Sunday's game against the Chiefs.

Both players missed all three days of practice this week and were listed as doubtful on the official injury report on Friday.

Jones, who sprained his knee against Carolina in Week 3, missed last Sunday's 17-10 loss to the Broncos due to the ailment.

Williams suffered a rib injury versus Denver last week.
