Allen Park — The Detroit Lions appeared to have perfect attendance for Wednesday's practice, with every player on the roster in a jersey and a helmet for the portion of open to the media, but linebacker Jarrad Davis and running back Theo Riddick were listed as non-participants on the afternoon report. 

Riddick, who missed all of last week with a knee injury, including Sunday's win over the Dolphins, was on the field with the running backs during individual drills, but wasn't participating.

Davis, on the other hand, had a long talk with coach Matt Patricia during the team's stretching period before the linebacker was worked on by the team's training staff. He was listed as out with a calf injury. 

Additionally, cornerback Darius Slay also spent extended time with the training staff during the early portions of practice. He was limited with a toe injury. 

Also limited for the Lions were defensive end Ziggy Ansah (shoulder), wide receiver Golden Tate (ankle) and running back Ameer Abdullah (ankle).
