DT John Atkins
LB Austin Bryant
DT P.J. Johnson
OT Ryan Pope
Atkins is not a rookie but qualifies for participation in the rookie camp by not having a full season under his belt. He played in two games for Detroit last fall.
The active/NFI list means the player has reported but is unable to practice because of an injury that occurred off the field. This can include collegiate injuries carrying over to the NFL.
In addition, the Lions placed WR Chris Lacy on the active/physically unable to perform list.
