Detroit Lions running back Theo Riddick (wrist) is not practicing on Friday.
Riddick hasn't practiced all week, and it's looking unlikely that he suits up against the Green Bay Packers on Sunday. Look for Zach Zenner to continue to play a big role in Riddick's absence.
Our models project Zenner for 9.0 carries, 30.4 yards and 0.16 touchdowns in Week 17.
