ALLEN PARK — Safety is a position of concern with the announcement this morning that Erik Coleman (ankle) has been placed on Injured Reserve list, ending his season.

He was injured in the game at Dallas and missed the Monday night game along with starting safety Amari Spievey (hamstring).

It’s a move the Lions may have seen coming because they signed S Vincent Fuller last week. Even though he didn’t have much practice time with Detroit, he saw action on Monday night.

Spievey could be back Sunday to face the 49ers. Although the Lions didn’t practice Wednesday he was listed on the injury report that speculated he would have been limited in practice.

Signing Finley may mean that tight end Tony Scheffler, who suffered a concussion on Monday night, may have a long-term injury.
