Cowboys running back Rico Dowdle fell ill on Sunday. He won’t be playing on Sunday Night Football.

The Cowboys counted Dowdle among their inactives.

The team was already expected to use veteran Dalvin Cook, who was called up from the practice squad for his Cowboys debut.

The Cowboys’ other inactive players are cornerback Caelen Carson (shoulder), defensive end Micah Parsons (ankle), quarterback Trey Lance, cornerback Andrew Booth Jr. and offensive tackle Matt Waletzko. Lance is the third quarterback in emergency.

Dallas only has three active cornerbacks tonight, although Israel Mukuamu can play corner if something happens to Trevon Diggs, Jourdan Lewis and/or Amani Oruwariye.

The 49ers will have tight end George Kittle and wide receiver Deebo Samuel, whose play was questionable.

The team’s inactives include offensive lineman Ben Bartch, quarterback Joshua Dobbs, defensive tackle Kevin Givens (groin), linebacker Jalen Graham, wide receiver Jauan Jennings (hip), kicker Jake Moody (right ankle) and cornerback Rock Ya-Sin. Dobbs will serve as the third emergency quarterback.

Anders Carlson, who was called up from the practice squad, will play for the 49ers for the second consecutive season.
