The Cowboys are closing in on their regular season opener. Dallas will visit the NFC East rival New York Giants on Sunday night at MetLife Stadium. The Cowboys will be aiming for their fifth straight win over the Giants. Starting left guard Tyler Smith, defensive end Sam Williams and safety Donovan Wilson did not participate in Wednesday's practice. Cornerback Jourdan Lewis was listed as a full participant for the first time in his return from a foot injury that limited him to six games last season.
