Smith missed the past two games with a groin injury, and the Cowboys allowed 12 sacks. Bailey hasn’t kicked since injuring his groin during the Cowboys’ victory over San Francisco on Oct. 22.

The Chargers’ inactives are quarterback Cardale Jones, wide receiver Geremy Davis, tight end Sean Culkin, running back Branden Oliver, linebacker James Onwualu, tackle Michael Ola and defensive end Jerry Attaochu.
