Lions' Riddick out against Giants, Zenner active

East Rutherford, N.J. -- The Detroit Lions held out a sliver of hope Theo Riddick could play against the New York Giants, listing him as doubtful on Friday's injury report. But his injured wrist didn't show enough improvement over the weekend and the starting running back has been scratched from the lineup for a second consecutive week.
It wasn't all bad news in the backfield. Running back Zach Zenner, who suffered a concussion during last weekend's win over the Bears, has cleared protocol and is active against the Giants. He's expected to back up rookie Dwayne Washington.
Also inactive for the Lions are offensive tackle Cornelius Lucas, defensive tackle Stefan Charles, defensive end Corey Lemonier, center Travis Swanson, wide receiver TJ Jones and quarterback Jake Rudock.
Swanson, the team's starting center, had been ruled out earlier in the week with a concussion.
Charles is a healthy scratch for the first time since Week 5. Detroit has five defensive tackles on the roster and typically keep four active. Last week, defensive coordinator Teryl Austin explained the decision is made based on which players have the best week of practice.
