ALLEN PARK — Long snappers really aren’t missed until they’re not there. Don Muhlbach, the Lions’ long snapper, was not at practice today (Tuesday). It’s unknown if he’s injured and the Lions will not produce an injury report today.

Center Dominic Raiola was taking the long-snapping duties during practice.

Safety Chris Harris was on the sidelines, but not participating in practice. He was tested for a concussion during Sunday’s game but no results were released.

Safety Louis Delmas who had minor surgery Saturday to repair his torn MCL also did not practice.

CB Don Carey also did not practice.

DT Corey Williams (hip) was out along with Kyle Vanden Bosch who was likely taking a rest day.
