Lions new NT Damon Harrison active; Ziggy Ansah, Theo Riddick remain out

Kickoff at 1 p.m. at Ford Field

DETROIT >> Damon “Snacks” Harrison, who was acquired in a trade with the Giants on Wednesday, is active today against the Seattle Seahawks at Ford Field.

The run-stuffing nose tackle practiced with his new team on Thursday and Friday. He said he was working night and day to learn the playbook. Coach Matt Patricia would not say on Friday if Harrison would be familiar enough with the defense to play. Apparently the veteran is a quick learner.

Lions defensive end Ziggy Ansah remains out. Ansah played in 19 snaps in the opening loss to the Jets before he injured his shoulder. He has not played a snap since then. He was limited in practice all week and listed as questionable on Friday’s injury report.

Linebacker Jarrad Davis (calf) is active after he had been listed as questionable. He had limited practice on Thursday and Friday after sitting out on Wednesday.

Wide receiver T.J. Jones is inactive with Brandon Powell possibly seeing his first action.

Running back Theo Riddick (knee) was ruled out on Friday. It will be the second straight game he missed.

Other Lions inactives: Cornerback Lenzy Pipkins, defensive end Kerry Hyder, guard Joe Dahl and offensive lineman Andrew Donnal.

The Lions and Seahawks both enter the game at 3-3. Kickoff is 1 p.m., on FOX.
