ARLINGTON, Texas -- The Baltimore Ravens' challenge to upset the Dallas Cowboys just got tougher.
Cornerback Jimmy Smith is inactive Sunday with a back injury. The Ravens have to figure out a way to match up against Cowboys wide receiver Dez Bryant.
The NFL's top-ranked defense was prepared going into the game to be without Smith, who was officially listed as doubtful. The Ravens' options at cornerback are Tavon Young, Shareece Wright, Jerraud Powers and Anthony Levine.
The other inactives are: LB Elvis Dumervil (foot), guard Alex Lewis (ankle), tight end Crockett Gillmore (thigh), running back Lorenzo Taliaferro, offensive lineman Ryan Jensen and cornerback Asa Jackson.
