Cowboys running back Rico Dowdle developed an illness on Sunday. He won’t be playing on Sunday Night Football.

The Cowboys listed Dowdle among their inactives.

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

The Cowboys’ other inactives 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 emergency third quarterback.

Dallas only has three cornerbacks active tonight, although Israel Mukuamu could 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, who were questionable to play.

The team’s inactives are offensive lineman Ben Barch, 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 emergency third quarterback.

Anders Carlson, who was undrafted from the practice squad, will kick for the 49ers for the second straight week.
