Lions’ Swanson out, Riddick and Slay doubtful

Allen Park -- The Detroit Lions have ruled out center Travis Swanson for a third consecutive week, but are holding out hope running back Theo Riddick and cornerback Darius Slay will be able to play Monday night against the Dallas Cowboys.

Swanson is still working his way back from a concussion he suffered against the New Orleans Saints. He played every snap in that win, with symptoms showing up after the game. Rookie Graham Glasgow has been starting in Swanson’s place, with Laken Tomlinson playing left guard.

Slay (hamstring) and Riddick (wrist) have been listed as doubtful after not practicing this week. It would be a surprise if either played. The Lions promoted Alex Carter off the practice squad on Saturday to provide cornerback depth.

The Cowboys have ruled out multiple players, including starting cornerback Morris Claiborne and defensive end Demarcus Lawrence. Wide receiver Dez Bryant (back), linebacker Sean Lee (knee) and offensive tackle Tyron Smith (back/knee) are questionable.
